摘要

研究证实了含铑纳米复合材料与碳纳米点以及硅、铝和锆氧化物在高温水转移反应中的催化活性。支撑物的作用在于调节活性成分（Rh）的表面浓度及其定位。使用低比表面的支撑物可促进活性成分在外表面的定位，从而减小支撑的 Rh 粒子之间的距离，这对反应中间产物的表面迁移非常重要。

Catalytic Properties of Carbon Dots Based Rh-Containing Nanocomposites on Si, Al, Zr Oxides in the Water Shift Reaction

The catalytic activity of rhodium-containing nanocomposites with carbon nanodots and Si, Al and Zr oxides in high-temperature water shift reaction has been established. The role of support lies in regulation of the surface concentration of the active component (Rh) and its localization. The use of the support with a low specific surface promote the localization of the active component on the external surface that leads to the decrease of the distance between supported Rh particles, which is important for the surface migration of intermediate products of the reaction.
