摘要：
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 surface 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 Mo2C with small particle size and high specific surface area, which has better prospects for catalytic application. © All Right Reserved.
