摘要
纳米金属催化剂的制备方法包括化学法和物理法。化学法中主要有溶胶-凝胶法、沉淀法、溶剂热合成法、微乳法和水解法等;物理法主要有气相凝聚法、溅射法和机械研磨法等。其中化学法中的溶胶-凝胶法及沉淀法应用最广。对纳米金属催化剂的制备方法进行了比较,并简要论述了制备及应用过程中存在的主要问题。
The preparation methods of metal nanocatalysts include chemical methods and physical methods. The chemical methods include sol-gel, precipitation, solvo-thermal synthesis, microemulsion, hydrolization, etc. The physical methods include gas coacervation, sputtering, mechanical milling, etc. The sol-gel and precipitation of chemical methods are applied widely. The preparation methods of metal nanocatalysts are compared, and the existing main problems in the preparation and application processes are discussed briefly.
