【摘要】

：

自从1973年Levy和Boudart1报道了碳化物具有类似贵金属的电子结构和催化特性以来，过渡金属碳化物作为一种新材料已引起了人们的极大兴趣。过渡金属碳化物(TMCs)是由碳和金属所形成的“间充性合金”，其制备通常都需要较高的反应温度和较长的反应时间，而且制得的产物颗粒尺寸较大，一般在微米范围，形貌和尺寸难以调控，这种情况严重阻碍了过渡金属碳化物的广泛应用。

新型负载Ru催化剂及其在一氧化碳氧化反应中的应用

能源节约与重复利用是当今社会面临的重要问题。金属Ru以其良好的催化氢化、碳碳键偶联的能力在能源转化利用中被广泛应用[1]。然而金属Ru的价格昂贵,负载型Ru催化剂虽然可以显著提高Ru分散度、降低成本,但是传统的负载方法制备的Ru催化剂往往会在高温反应中发生团聚烧结,因此需要发展具有高温稳定性、抗团聚、抗烧结的负载型Ru催化剂[2,3]。
