摘　　要：在介绍3D多枝状Pt基贵金属纳米晶形貌控制方法的基础上,对影响Pt基贵金属纳米催化剂催化活性的纳米粒子形貌结构、溶剂热处理导致的不同机理以及热处理工艺导致的纳米粒子形貌变化方面进行了综述。Based on the introduction of the shape controlled method of 3 D multi-branched Pt-based noble metal nanocrystals, the nanostructural grain morphology which can affect the catalyst active of Pt-based noble metal, solvent thermal treatment leading to different mechanisms and the morphology of the change of nanoparticles caused by thermal treatment were reviewed.

关 键 词：形貌控制方法 溶剂热处理 热处理
