Abstract ：
Three-dimensionally ordered macroporous (3DOM) Ce0.7Zr0.3O2-supported 0.7 Zr 0.3 O 2-supported Pd (xPd/3DOM x Pd/3DOM Ce 0.7 Zr 0.3 O 2 , x = 0.97, 1.49, and 2.10 wt%) catalysts were fabricated using the polymethyl methacrylate (PMMA) microspheretemplating and polyvinyl alcohol (PVA)-protected reduction methods. It was found that the x Pd/3DOM Ce 0.7 Zr 0.3 O 2 samples with surface areas of 31.9-38.2 m2/g 2 /g possessed a high-quality 3DOM architecture, with the Pd nanoparticles (NPs) being uniformly dispersed on the 3DOM Ce 0.7 Zr 0.3 O 2 surface. Among all of the samples, 1.49 Pd/3DOM Ce 0.7 Zr 0.3 O 2 showed the best CH4 4 combustion activity: The T 10% , T 50% , and T 90% (the temperatures at CH4 4 conversions = 10, 50, and 90%) were 269, 330, and 380 degrees C, respectively; specific reaction rate at 260 degrees C was 115.0 x 10-- 6 mol/(gPd Pd s), and turnover frequency at 260 degrees C (TOFPd) Pd ) was 28.8 x 10-- 3 s-1.-1 . The good catalytic performance of 1.49 Pd/3DOM Ce 0.7 Zr 0.3 O 2 was associated with the well-defined 3DOM structure, high Pd NP dispersion, rich adsorbed oxygen species, and strong interaction between Pd NPs and 3DOM Ce 0.7 Zr 0.3 O 2 . Interestingly, the 1.49 Pd/3DOM Ce 0.7 Zr 0.3 O 2 sample also exhibited superior water-tolerant performance. The product analysis results after the in situ introduction of isotopic water demonstrated that the excellent water resistance of 1.49 Pd/3DOM Ce 0.7 Zr 0.3 O 2 was due to the interaction of oxygen and water to form the peroxy hydroxyl species on the sample surface after the water pretreatment, which was beneficial for the combustion of methane.

Abstract ：
Reducing emissions of volatile organic compounds (VOCs) is an integral part of improving the quality of the atmospheric environment. Catalytic oxidation has become an effective means of treating low and medium concentration VOCs exhausts due to its advantages in terms of removal efficiency, energy saving and environmental protection. Due to the unique inherent properties of supported precious metal catalysts, they show good catalytic efficiency in VOCs emission reduction. In this study, the mesoporous Si-WO 3 support was first synthesized by the P123-assisted sol -gel method, and the x Pt/Si-WO 3 catalysts with the actual loadings ( x = 0.19, 0.48, and 0.81 wt%) of Pt nanoparticles (NPs) were then obtained, physicochemical properties of these materials were characterized using a variety of techniques, and their catalytic activities and water resistance for the oxidation of toluene were evaluated. The results showed that Pt NPs with an average particle size of 2.3-3.3 nm were highly dispersed on the mesoporous Si-WO 3 support, and the 0.81Pt/Si-WO 3 sample exhibited the highest catalytic activity for toluene oxidation at a space velocity of 20,000 mL/(g h) ( T 50% = 167 degrees C and T 90% = 180 degrees C; specific reaction rate at 160 degrees C = 8.54 mu mol/(g Pt s), turnover frequency (TOF Pt ) at 160 degrees C = 1.67 x 10 - 3 s - 1 , and apparent activation energy = 45 kJ/mol). The good catalytic performance of 0.81Pt/Si-WO 3 was associated with its large surface area, well dispersed Pt NPs, high adsorbed oxygen species concentration, large toluene adsorption capacity, and strong interaction between Pt NPs and mesoporous Si-WO 3 . The 0.81Pt/Si-WO 3 sample possessed excellent water resistance, and the introduction of 5 vol% or 10 vol% water vapor to the reaction system enhanced toluene oxidation since part of water vapor participated in the oxidation of toluene. In addition, the toluene oxidation pathway might obey the sequence of (adsorbed toluene + adsorbed oxygen species) -* benzyl alcohol -* (benzoic acid and benzaldehyde) -* maleic anhydride -* (carbon dioxide and water).

Abstract ：
Crystal facet and defect engineering are crucial for designing heterogeneous catalysts. In this study, different solvents were utilized to generate NiO with distinct shapes (hexagonal layers, rods, and spheres) using nickelbased metal-organic frameworks (MOFs) as precursors. It was shown that the exposed crystal facets of NiO with different morphologies differed from each other. Various characterization techniques and density functional theory (DFT) calculations revealed that hexagonal-layered NiO (NiO-L) possessed excellent low-temperature reducibility and oxygen migration ability. The (111) crystal plane of NiO-L contained more lattice defects and oxygen vacancies, resulting in enhanced propane oxidation due to its highest O 2 adsorption energy. Furthermore, the higher the surface active oxygen species and surface oxygen vacancy concentrations, the lower the C -H activation energy of the NiO catalyst and hence the better the catalytic activity for the oxidation of propane. Consequently, NiO-L exhibited remarkable catalytic activity and good stability for propane oxidation. This study provided a simple strategy for controlling NiO crystal facets, and demonstrated that the oxygen defects could be more easily formed on NiO(111) facets, thus would be beneficial for the activation of C -H bonds in propane. In addition, the results of this work can be extended to the other fields, such as propane oxidation to propene, fuel cells, and photocatalysis.

Abstract ：
Among the developed electrocatalysts, NiCr-layered double hydroxides (NiCr-LDH) are one of the most effective electrocatalytic materials for water oxidation. However, applications of such a kind of materials are practically limited due to their poor electric conductivity. In this work, the single-walled carbon nanotube (SWCNT) was doped to NiCr-LDH, and the LDH-based nanocomposites were synthesized using the one-step ultrasonic-assisted method. Physicochemical properties of the NiCr-LDH/SWCNT composites were characterized by means of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray (EDX) analysis, transmission electron microscopy (TEM), field emission-scanning electron microscopy (FE-SEM), and linear sweep voltammetry (LSV). The NiCr-LDH/SWCNT composites were used as effective nanomaterials for oxygen evolution reaction (OER) at a near neutral medium. The LSV results confirm that the overpotential of the NiCr-LDH/SWCNT-0.006 sample decreased to about 120 mV at pH = 9.5, as compared with that of the NiCr-LDH or NiCr-LDH-SWCNT-0.006 (prepared by the two-step method) sample. The high oxygen evolution activity of NiCr-LDH/SWCNT-0.006 was associated with the co-presence of the homogeneously dispersed NiCr-LDH, good electrochemical activity, and high electrical conductivity. In addition, the as-prepared optimized NiCr-LDH/SWCNT electrocatalyst was highly stable for the OER reaction. (c) 2022 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.

Abstract ：
Ethylene elimination can effectively inhibit the rapid aging of fruits and vegetables in storage and transportation. Improving the low-temperature activity, moisture resistance, and stability of Pt based catalysts is a challenge for catalytic oxidation of ethylene which is an effective elimination method. Herein, we constructed ultrasmall MnOx cluster (< 1 nm) on Pt particles via an alloy in situ transformation strategy, which created a large number of MnOx/Pt interfaces. Among all of the samples, 1.89Pt(2.20)Mn/TiO2 showed the highest catalytic activity in the oxidation of ethylene at a space velocity of 20,000 mL/(g h): T-50% = 34 degrees C and T-90% = 43 degrees C, specific reaction rate at 35 degrees C = 33.0 mu m degrees l/(g(Pt) s), and turnover frequency at 35 degrees C = 6.5 x 10(-3) s(-1). In addition, Pt2.20Mn/TiO2 also exhibited better water resistance and stability than Pt/TiO2. The results of XPS, H2O-TPD, C2H4-TPD, in situ DRIFTS, and (H2O)-O-18 isotopic tracing characterization revealed that the MnOx/Pt interfacial sites accelerated desorption of CO2 and enhanced the activation of surface active oxygen species (O-2 to O-2(2-)). Meanwhile, the numerous interfaces provide more active sites for ethylene adsorption and activation, reducing the inhibitory effect of adsorbed water on ethylene adsorption. It was concluded that the prohibited CO2 adsorption, and increased adsorbed oxygen species were responsible for the excellent catalytic performance and good stability of 1.89Pt(2.20)Mn/TiO2, while the more active sites for ethylene adsorption and activation were responsible for the good water resistance of 1.89Pt(2.20)Mn/TiO2.

Abstract ：
The cryptomelane-type manganese oxide (OMS-2)-supported Co (xCo/OMS-2; x = 5, 10, and 15 wt.%) catalysts were prepared via a pre-incorporation route. The as-prepared materials were used as catalysts for catalytic oxidation of toluene (2000 ppmV). Physical and chemical properties of the catalysts were measured using the X-ray diffraction (XRD), Fourier transform infrared spectroscopic (FT-IR), scanning electron microscopic (SEM), X-ray photoelectron spectroscopy (XPS), and hydrogen temperature-programmed reduction (H-2-TPR) techniques. Among all of the catalysts, 10Co/OMS-2 performed the best, with the T90%, specific reaction rate at 245 degrees C, and turnover frequency at 245 degrees C (TOFCo) being 245 degrees C, 1.23 x 10(-3) mol(toluene)/(g(cat).sec), and 11.58 x 10(-3) sec(-1) for toluene oxidation at a space velocity of 60,000 mL/(g.hr), respectively. The excellent catalytic performance of 10Co/OMS-2 were due to more oxygen vacancies, enhanced redox ability and oxygen mobility, and strong synergistic effect between Co species and OMS-2 support. Moreover, in the presence of poisoning gases CO2, SO2 or NH3, the activity of 10Co/OMS-2 decreased for the carbonate, sulfate and ammonia species covered the active sites and oxygen vacancies, respectively. After the activation treatment, the catalytic activity was partly recovered. The good low-temperature reducibility of 10Co/OMS-2 could also facilitate the redox process accompanied by the consecutive electron transfer between the adsorbed O-2 and the cobalt or manganese ions. In the oxidation process of toluene, the benzoic and aldehydic intermediates were first generated, which were further oxidized to the benzoate intermediate that were eventually converted into H2O and CO2.
