Metal-Oxide Interface for Heterogeneous Catalysis via Intensifying Activation of Reactant Molecules.
Metal-oxide interfaces (MOI) are pivotal in heterogeneous catalysis due to their unique interfacial properties. This review focuses on their applications in selective alcohol oxidation, environmental catalysis (e.g., CO oxidation, soot combustion), CO2 hydrogenation, dry reforming of methane (DRM), and alkane conversion. Research demonstrates that MOI effectively modulates catalytic performance. The advantages of MOI can be generally described as follows: (1) mitigates competitive adsorption to enhance catalytic activity; (2) simultaneously activates two reactants through strong metal-support interactions; (3) stabilizes nanoparticles against sintering under harsh reaction conditions. This review systematically summarizes MOI construction strategies and structure-performance relationships, aiming to provide a theoretical foundation and practical guidance for the rational design of high-performance, stable heterogeneous catalysts.
