摘要 ：
Designing highly efficient photocatalysts is significantly important to degrade the harmful pollutions in water. In this study, photocatalyst of Fe3O4-ED-rGO with dissolved HPV was successfully prepared and electron microscopy characterization revealed that large number of single tungsten/vanadium atom oxide (ST/VAO) was homogeneously deposited on Fe3O4 nanoparticles in SMAO-MrGO-ED sample and occupied the bivalent Fe2+ sites. Meanwhile, phase analysis confirmed that the Fe3O4 nanocomposites were mostly conversed from the reducted Fe2O3 by the hydrolysis of rGO-ED-HPV. Such a highly dispersed monatomic adsorption on the bivalent Fe2+ of polycrystalline SMAO-MrGO-ED nanocomposite not only benefits for the visible light absorption from 2.7 eV to 2.10 eV, but also offers abundantly active sites to get the highest activity of 98.43% and 98.12% for ciprofloxacin (CF) and ibuprofen (IBF) photodegradation, respectively. All these discoveries give us a new insight to design the photocatalysts with high photodegradation efficiency, low cost, short reaction time and good reusability.

摘要 ：
Manganese oxide supported Pt single atoms (Pt-1/MnOx) are prepared by the molten salt method. Catalytic oxidation of toluene and iso-hexane, typical emissions from furniture paints industry, is tested. Pt-1/MnOx shows poor and high catalytic stability for toluene and iso-hexane oxidation, respectively. Enhancement in the catalytic stability for toluene oxidation is observed after the hydrogen reduction treatment of Pt-1/MnOx at 200 degrees C. The hydrogen treated catalyst possesses the weaker Mn-O bonds and lower coordination number of Pt-O, with superior mobility of lattice oxygen and appropriate toluene adsorption. Balancing lattice oxygen mobility and volatile organic compounds adsorption is important for the catalytic stability of Pt-1/MnOx. For the oxidation of toluene and iso-hexane mixture, owing to the competitive adsorption, iso-hexane oxidation is greatly inhibited, while toluene oxidation is not influenced. The present Pt-1/MnOx catalyst holds promising prospect in furniture paints industry applications because of high catalytic stability and water resistance ability.

摘要 ：
Bimetallic compounds are a kind of important catalytic materials in heterogeneous catalysis. In this work, we first employed n-butyllithium as reducing agent to synthesize Ir and IrFex (x is the Fe/Ir molar ratio and equal to 0.49, 0.90, and 2.80) nanocrystals (NCs), and then used an adsorption strategy to load them on the surface of ordered mesoporous ceria (meso-CeO2) derived from the KIT-6-templating route to obtain the 0.48 wt% Ir/mesoCeO2 (denoted as 0.48Ir/meso-CeO2) and 0.53-0.89 wt% IrFex/meso-CeO2 (denoted as 0.53IrFe0.49/meso-CeO2, 0.59IrFe0.90/meso-CeO2, and 0.89IrFe2.80/meso-CeO2) samples. Physicochemical properties of the samples were characterized by means of various techniques. It is shown that all of the samples possessed a cubic crystal phase, an ordered mesoporous architecture, and a surface area of 84-124 m2/g, in which the IrFex NCs with an average size of ca. 2 nm were highly dispersed on the meso-CeO2 surface. Among all of the samples, 0.59IrFe0.90/mesoCeO2 performed the best for acetylene combustion (T10% =155 degrees C, T50% =162 degrees C, and T90% =165 degrees C at space velocity = 20,000 mL/(g h)). Furthermore, 0.59IrFe0.90/meso-CeO2 showed good water- and carbon dioxideresistant performance, and its partial deactivation due to the introduction of SO2 was reversible. The possible reaction mechanisms over Ir/meso-CeO2 or IrFex/meso-CeO2 were also discussed. We conclude that the well dispersed IrFe0.90 NCs, high adsorbed oxygen and acetylene amounts, low-temperature reducibility, and strong interaction between IrFe0.90 NCs and meso-CeO2 were responsible for the good catalytic performance of 0.59IrFe0.90/meso-CeO2.

摘要 ：
A series of three-dimensionally ordered macroporous (3DOM) nickel-copper mixed oxides (with the NiO/CuO molar ratios of 3 : 3, 3 : 2, and 3 : 1) calcined at various temperatures (450, 550, and 650 degrees C) were prepared using the dual-templating (Pluronic P123 and polymethyl methacrylate (PMMA)) method in a mixed solution of ethylene glycol and methanol with different volumetric ratios (1 : 2, 1 : 1.5, and 1 : 1). The sample obtained after the use of P123 and PMMA exhibited a much higher catalytic activity for CO oxidation, over which a complete CO conversion was achieved at 138 degrees C, CO/O-2 volumetric ratio = 2 : 5, and space velocity = 60,000 mL/(g h), and this catalyst possessed good stability in the presence of water vapor in the feed stream. The large surface area, high oxygen adspecies concentration, good low-temperature reducibility, and unique nanovoid 3DOM structure were accountable for the superior catalytic performance of the sample prepared by the dual P123- and PMMA-templating method.

摘要 ：
To improve the removal capacity of NO + O2 effectively, the alkaline earth metal-doped order mesoporous carbon (A-C-FDU-15(0.001) (A = Mg, Ca, Sr and Ba)) and Mg-C-FDU-15(x) (x = 0.001−0.003) samples were prepared, and their physicochemical and NO + O2 adsorption properties were determined by means of various techniques. The results show that the sequence in (NO + O2) adsorption performance was as follows: Mg-C-FDU-15(0.001) (93.2 mg/g) > Ca-C-FDU-15(0.001) (82.2 mg/g) > Sr-C-FDU-15(0.001) (76.1 mg/g) > Ba-C-FDU-15(0.001) (72.9 mg/g) > C-FDU-15 (67.1 mg/g). Among all of the A-C-FDU-15(0.001) samples, Mg-C-FDU-15(0.001) possessed the highest (NO + O2) adsorption capacity (106.2 mg/g). The species of alkaline earth metals and basic sites were important factors determining the adsorption of NO + O2 on the A-C-FDU-15(x) samples, and (NO + O2) adsorption on the samples was mainly chemical adsorption. Combined with the results of (NO + O2)-temperature-programmed desorption ((NO + O2)-TPD) and in situ diffused reflectance infrared Fourier transform spectroscopy (DRIFTS) characterization, we deduced that there were two main pathways of (NO + O2) adsorption: one was first the conversion of NO and O2 to NO2 and then part of NO2 was converted to NO2− and NO3−; and the other was the direct oxidation of NO to NO2− and NO3−. © 2020

摘要 ：
In this work, we constructed a red phosphorus (RP)/TiO2 composite system via a chemical vapor deposition strategy. The evolution of the fibrous phased RP nanorods on the surface of anatase TiO2 spheres was rationally adjusted by controlling the composition of precursors. The optimal RP/TiO2 composite exhibited a significantly enhanced visible-light-driven photocatalytic H2 generation rate of 681 mu mol h-1 g-1. The tightly interior surface bonding between RP and TiO2 greatly promoted the efficient charge transfer and redistribution by suppressing the charge recombination and self-trapping processes within TiO2, resulting in prolonged lifetimes of the active charges during the photocatalytic process as investigated in detailed using femtosecond time-resolved transient absorption (fs-TA) spectroscopy.

摘要 ：
The low-cost and environmentally benign elemental red phosphorus ( RP) is a new class of photocatalysts with tunable bandgaps (ca. 1.5-2.4 eV) and has a strong visible-light response. It has been considered as a promising metal-free photocatalyst for solving the energy crisis and environmental problems. Unfortunately, due to the low-charge carrier mobility, and serve charge trapping effects, its photocatalytic activity is still restricted in comparison with the traditional compound photocatalysts. Considerable efforts, such as morphology modification, cocatalysts addition, heterostructure construction, charge trapping mitigation, have been conducted to improve the photocatalytic activity of the RP photocatalysts. In this review, the physical and chemical properties and the synthetic strategies of the RP photocatalysts were summarized along with the application in environmental remediation accompanied by the photocatalytic reaction mechanism. Finally, an overview and outlook on the problems and future avenues in designing and constructing advanced RP photocatalysts were also proposed. (C) 2021 Elsevier Ltd. All rights reserved.

摘要 ：
Improved photocatalytic activities in highly ordered porous photocatalysts are often attributed to the larger surface area, higher light absorption, and suppressed charge recombination. Other underlying reasons for the improved charge transport, however, remain elusive at this stage. Herein, 3DOM BiVO4 photocatalysts are examined to understand the carrier dynamics and their effects in photocatalytic water splitting. Quantum confinement arising from the ultrathin and crystalline wall upshifted its conduction band, enabling photocatalytic proton reduction to hydrogen gas under visible-light illumination. Time-resolved microwave conductivity spectroscopy reveals its similar to 6 times higher charge mobility and longer charge diffusion length relative to the bulk counterpart. The long lifetime (similar to 360 ns) of 3DOM BiVO4 with a power-law decay suggests the improved charge separation and the formation of shallow trapping states. Further investigation by Kelvin probe force microscope discloses a built-in electric field with upward band bending from the internal wall to the interconnection part of 3DOM BiVO4.

摘要 ：
The Ni-loaded cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2) catalysts (xNi/OMS-2: x = 1, 3, 5, and 10 wt%) were prepared by a pre-incorporation method. Physicochemical properties of the as-synthesized materials were characterized by means of various techniques, and their catalytic activities for CO, ethyl acetate, and toluene oxidation were evaluated.The loading of Ni played an important role in improving physicochemical propertiesof OMS-2. Among all of the samples, 5Ni/OMS-2 exhibited the best catalytic activity, with the T-90 being 155 degrees C for CO oxidation at a space velocity (SV) of 60,000 mL/(g center dot h), 225 degrees C for ethyl acetate oxidation at an SV of 240,000 mL/(g center dot h), and 300 degrees C for toluene oxidation at an SV of 240,000 mL/(g center dot h), which was due to its high Mn3+ content and O-ads concentration, good low-temperature reducibility and lattice oxygen mobility, and strong interaction between the Ni species and the OMS-2 support. In addition, catalytic mechanisms of the oxidation of three pollutants over 5Ni/OMS-2 were also studied. The oxidation of CO, ethyl acetate, and toluene over the catalysts took place first via the activated adsorption, then intermediates formation, and finally complete conversion of the formed intermediates to CO2 and H2O.

摘要 ：
The design and synthesis of g-C3N4 with favourable physical-chemical architecture are important factors in influencing its photoactivity. Herein, a phosphorus (P) vapor assisted synthetic strategy was employed to fabricate the P-doped hollow g-C3N4 photocatalysts with ultrathin shell structure (< 25 nm in thickness). The doping of P and the compression of shell thickness of the hollow g-C3N4 were induced simultaneously by the P vapor during the heating process. The as-prepared P-doped ultrathin hollow g-C3N4 sphere (P/UH-CNS) photocatalysts exhibited enlarged surface area and light responsive range, and improved charge transportation efficiency by suppressing the charge recombination and self-trapping within g-C3N4. These resulted in a high photocatalytic hydrogen evolution rate of 9653 mu mol h-1 g-1. The charge dynamics in this P/UH-CNS system was revealed in detail by using the ultrafast time-resolved spectroscopy.
