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 ：
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 ：
The PdPtVOx/CeO2-ZrO2 (PdPtVOx/CZO) catalysts were obtained by using different approaches, and their physical and chemical properties were determined by various techniques. Catalytic activities of these materials in the presence of H2O or SO2 were evaluated for the oxidation of ethylbenzene (EB). The PdPtVOx/CZO sample exhibited high catalytic activity, good hydrothermal stability, and reversible sulfur dioxide-poisoning performance, over which the specific reaction rate at 160 degrees C, turnover frequency at 160 degrees C (TOFPd or Pt), and apparent activation energy were 72.6 mmol/(g(Pt)& sdot;sec) or 124.2 mmol/(g(Pd)& sdot;sec), 14.2 sec(-1) (TOFPt) or 13.1 sec(-1) (TOFPd), and 58 kJ/mol, respectively. The large EB adsorption capacity, good reducibility, and strong acidity contributed to the good catalytic performance of PdPtVOx/CZO. Catalytic activity of PdPtVOx/CZO decreased when 50 ppm SO2 or (1.0 vol.% H2O + 50 ppm SO2) was added to the feedstock, but was gradually restored to its initial level after the SO2 was cut off. The good reversible sulfur dioxide-resistant performance of PdPtVOx/CZO was associated with the facts: (i) the introduction of SO2 leads to an increase in surface acidity; (ii) V can adsorb and activate SO2, thus accelerating formation of the SOx2- (x = 3 or 4) species at the V and CZO sites, weakening the adsorption of sulfur species at the PdPt active sites, and hence protecting the PdPt active sites to be not poisoned by SO2. EB oxidation over PdPtVOx/CZO might take place via the route of EB -> styrene -> phenyl methyl ketone -> benzaldehyde -> benzoic acid -> maleic anhydride -> CO2 and H2O.(c) 2023 The Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences.

Abstract ：
Water oxidation is an optimistic pathway for hydrogen generation with high quality. In this work, nest-like nickel iron-layered double hydroxide (NiFe-LDH) nanomaterials were successfully prepared using the ethylene glycol-assisted hydrothermal strategy. Morphological and structural studies showed that in the assistance of ethylene glycol (EG), morphologies of the NiFe-LDH nanomaterials were modified, and their surface areas were enhanced. The nano nest-like NiFe-LDH-EG3 derived with 3.0 mL of EG exhibited an excellent oxygen evolution reaction (OER) activity with a low overpotential of about 400 mV at a current density of 10 mA/cm2 and a Tafel slope of 79 mV/dec in neutral media, and such an outstanding OER activity was attributed to the modified morphology, good crystallinity, and high surface area of the nest-like NiFe-LDH-EG3.

Abstract ：
Semiconductor photocatalytic technology has shown great prospects in converting solar energy into chemical energy to mitigate energy crisis and solve environmental pollution problems. The key issue is the development of high-efficiency photocatalysts. Various strategies in the state-of-the-art advancements, such as heterostructure construction, heteroatom doping, metal/single atom loading, and defect engineering, have been presented for the graphitic carbon nitride (g-C3N4)-based nanocomposite catalysts to design their surface chemical environments and internal electronic structures to make them more suitable for different photocatalytic applications. In this review, nanoarchitecture design, synthesis methods, photochemical properties, potential photocatalytic applications, and related reaction mechanisms of the modified high-efficiency carbon nitride-based photocatalysts were briefly summarized. The superior photocatalytic performance was identified to be associ- ated with the enhanced visible-light response, fast photoinduced electron-hole separation, efficient charge migration, and increased unsaturated active sites. Moreover, the further advance of the visible-light harvesting and solar-to-energy conversions are proposed. (C) 2022 The Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences.
