Summary: Cu-Co mixed oxides were found to exhibit good catalytic performance in the oxidation of toluene, with Cu0.2Co showing the best performance. However, in propane oxidation, the activity of the catalysts decreased as the copper content increased due to the low intrinsic activity of CuO. Various factors affecting the oxidation reactions were studied, including the presence of CO2, water vapor and NO.

Summary: Co, Ce and Co-Ce nanofibers were synthesized by electrospinning method and applied to gas-solid and solid-solid-gas reactions. Different activity trends were observed in CO oxidation and combustion of diesel soot, with Co-Ce nanofibers showing the highest activity for soot combustion and Co exhibiting the highest activity for CO oxidation. The temperature range for maximum combustion rate was narrow for soot combustion and wider for CO oxidation. The high activity for soot oxidation was attributed to multiple contact points between fibers and soot particles, while the trend observed for CO oxidation was related to the higher redox capacity of Co.

Summary: The catalytic combustion of trichloroethylene (TCE) was studied using cerium-based catalysts, which exhibited surprising catalytic activity. MnOx was doped into CeO2 using a citric acid sol-gel method, and the effect of Mn content on the physicochemical properties and catalytic activities of MnOx-CeO2 mixed oxides was systematically investigated. The introduction of MnOx into CeO2 significantly improved the catalytic activity and reaction stability of the CeO2 catalyst, and the catalytic activity could be maintained for over 100 hours under an air atmosphere. Moreover, a possible reaction mechanism and catalytic cycle for the catalytic combustion of TCE over MnOx-CeO2 mixed oxide catalysts are proposed.

Summary: Earth-abundant transition metal oxides, such as CoO and Co3O4, grown on carbon fiber paper (CFP) electrodes, exhibit different catalytic activities for the oxidation of glycerol, diols, and monohydric alcohols. In situ electrochemical tests show that the CoO/CFP electrode has higher catalytic activity than the Co3O4/CFP electrode, with lower interfacial impedance, higher charge transfer, and faster oxidation rate. The CoO/CFP electrode also produces value-added products with high selectivity and efficiency at low energy consumptions. Theoretical calculations highlight the importance of octahedrally coordinated Co-O sites in the adsorption, activation, and oxidation of C3-C1 alcohols. These findings provide insights for the design of highly efficient transition metal oxide catalysts for alcohol oxidation.

Summary: Catalytic total oxidation is an efficient technique for treating VOCs emitted by solvent-based industrial processes. However, studies on the oxidation of VOCs in combination with other pollutants are very limited, despite being a crucial step before industrial application. It is important to carefully select both the catalytic material and reaction conditions for treating effluents loaded with VOCs, as the oxidation behavior is influenced by the reaction mixture.

Summary: In this study, the activity, selectivity, and stability of a supported nickel catalyst were compared under classical heating conditions and magnetically activated catalysis using iron wool as a heating agent. The catalyst was prepared via an organometallic decomposition method and thoroughly characterized. Magnetic induction heating achieved a higher CO2 conversion rate of 85% compared to 78% for thermal conditions at a slightly lower temperature. Both processes remained stable for 45 hours on stream. The potential of magnetic heating-mediated methanation for pilot-scale reactors was demonstrated.

Summary: In this study, MnCoAl mixed oxides were prepared using the LDH approach with various textural and structural frameworks, showing that the catalytic activity was influenced by the Mn/Co ratio and gas atmosphere. Rietveld refinement was utilized to estimate phase proportions, revealing that the spinel and lamellar phases improved redox properties and active sites in the oxides. Lowering cobalt content increased catalytic activity at low temperatures, while using an N2 atmosphere during synthesis helped prevent undesirable phase formation. The presence of an oxygen-free atmosphere during LDH synthesis positively affected ethanol transformation to CO2 over the oxide catalysts.
