CuH分解制备铜基催化剂及其催化CO氧化反应的活性研究

宏量制备CuH纳米粒子，并通过CuH纳米粒子在不同气氛下的热分解制备了具有不同组成和结构的铜基催化剂．CuH纳米粒子在N2中分解制备的催化剂表现出最好的CO催化氧化活性，而CuH纳米粒子在O2中分解制备的催化剂表现出最差的CO催化氧化活性．基于上述结果讨论了铜基催化剂在CO氧化反应中的结构-性能关系．

Preparation of Cu-based catalysts via the decomposition of Cull precursor and their catalytic activities in CO oxidation

CuH nanoparticles were synthesized and employed as the precursor for the preparationof unsupported Cu-based catalysts. Thermal decomposition of Cull under different atmosphericconditions led to the formation of Cu-based catalysts with different compositions and structures.The catalyst prepared by the CuH decomposition under the N2 atmosphere exhibits the bestcatalytic performance in CO oxidation whereas the catalyst prepared by the Cull decompositionunder the O2 atmosphere exhibits the worst catalytic performance. The structure-activity relationof various Cu-based catalysts was also discussed.
