摘要

有序介孔碳是一种具有宽孔径、规则孔道结构、高比表面积和大孔容的纳米结构材料，具有很高的导电性及化学稳定性，是一种非常优良的载体材料。过渡金属碳化物因其结构相似性，具有一系列类似贵金属的性质，可作为贵金属替代材料，用于多相催化过程。但过渡金属碳化物多数粒径大、比表面积低，不利于催化活性，因此，采用熔盐法合成了多种有序介孔碳负载的过渡金属碳化物，并通过SEM、TEM、XRD、BET等方法对样品进行了一系列表征。结果表明，该方法能有效制备碳负载的TiC、Mo

C等金属碳化物，且具有较小的颗粒尺寸和较高的比表面积，将有较好的催化应用前景。

Abstract

Ordered mesoporous carbon is a kind of nanostructured material with regular pore structure

high specific surface area and large pore volume. It is also a very good carrier material. Meanwhile

transition metal carbides have a series of properties that are similar to precious metals because of their structural characteristics. They can be used as catalysts with high activity in theory for heterogeneous catalytic processes to replace precious metals. However

transition metal carbides greatly affect the catalytic activity due to their low specific su

rface area and large particle size. Therefore

a variety of ordered mesoporous carbon-supported transition metal carbides were synthesized by molten salt method

and the samples were characterized by SEM

TEM

XRD and BET. The results show that the method can form carbon-supported metal carbides such as TiC and Mo

C with small particle size and high specific surface area

which has better prospects for catalytic application.
