纳米限域体系的催化特性

Catalytic characters of the nano-confined systems

本文以限域体系对电子调控为基础和出发点,系统介绍体系尺寸变化导致催化特性调控的实验和理论研究结果,通过纳米银催化选择氧化和碳管限域的纳米粒子高效催化合成气转化等实例进一步阐述基于限域效应的催化"尺度调控法"的概念.

In the present work, the unique characters of the nano-confined systems for catalysis are demonstrated. The emphasis is on the synergetic effects of the electron confinements derived from the nano-particle and the carbon nanotube channels, as well as the nano-layers with subsurface metals. The catalytic reactions, such as the selective oxidation and the conversion of syngas, have been employed to illustrate the novel concept of size-modulating in catalysis.
