摘要:

Colloidal synthesis has made great progress by controlling the size, shape, and composition of nanoparticles. An ultimate goal of industrial catalysis is to achieve the highest catalytic activity and selectivity toward only one desired product, while maintaining high stability against deactivation. Many catalytic reaction studies have been demonstrated enhancement of reaction rate and change of selectivity with the optimum nanoparticle size and shape. In addition, catalytic behaviors can also be altered at oxide-metal interfaces by creating the strong metal-support interaction. In this presentation, gas-phase heterogeneous catalytic reactions including benzene, toluene, and hexane hydrogenation and carbon monoxide oxidation, are introduced by demonstrating how the size, shape, and composition of nanoparticles and oxide-metal interfaces affect catalytic performance at the molecular level.
