催化剂微尺度结构与反应动力学
Microstructures and reaction kinetics of catalysts
摘要
Abstract
Traditional catalytic reaction kinetics studies focus on macroscopic variables and properties (such as temperature and concentration sensitivity) and can be used to guide the optimal design of industrial reactors, but pay little attention to the effects of catalyst microscale structures and properties. It cannot therefore be used to guide the optimal design of the catalyst. This review mainly discusses the development and application of multifaceted kinetics analysis method, which can discriminate the dominant active sites of supported metal catalysts, and the possibility to use the activation entropy (ΔS0*) as an experimentally measurable descriptor of catalytic reaction rate, which can be fine-tuned by tailoring the electronic properties of supported metal nanoparticles in terms of the surface chemistry and properties of carbon supports. It can extend the application of the kinetics analysis from the reactor design to the catalyst design.关键词
