Abstract: 

We delineate the persuasive examples for synthesizing supported metal/oxide nanoparticle catalysts with controllable surfacial and interfacial nanostructures. Such catalysts enhance the product selectivities in hydrogenation of reactants with more than one reducible groups, and improve the catalytic activities in the oxidation of hydrocarbons. Several routes involving single-site Sn modification, morphology control, and construction of strong-metal supported interactions are introduced. In addition, a series of metal-zeolite catalysts are developed by fixing by fixing metal nanoparticle inside of zeolite crystals to form a core-shell structure. In the hydrogenation of substituted nitroarenes, oxidative cyanation of hydrocarbons, transformation of several C1 molecules and biomass-platform molecules, the catalysts exhibit superior selectivity and durability to outperform both conventional metal nanoparticles supported on zeolite crystals and the commercial catalysts.
