作者利用热重方法研究了活性炭载金属组份催化剂对载体活性炭的催化氧化反应动力学,对催化剂结构进行了表征。研究结果表明:Cu/C催化剂比同系列Fe/C、Ca/C、Zn/C等催化剂有许多独特的性能,如结构稳定、反应活性对还原处理敏感,表面含氧功能团增多等。 Cu/C中金属铜活性组份同载体炭之间可相互作用产生新的活性中间体I(CuO、Cu~(2+))离子
The authors used the thermogravimetric method to study the kinetics of catalytic oxidation of activated carbon supported on activated carbon supported on activated carbon. The structure of the catalyst was characterized. The results show that Cu / C catalyst has many unique properties over the same series of catalysts such as Fe / C, Ca / C, Zn / C, such as stable structure, sensitive reactivity to reduction, and increased oxygen functional groups on the surface. Cu / C copper in the active component with the carrier carbon can interact with each other to produce a new active intermediate I (CuO, Cu ~ (2+)) ions
