非晶态合金催化剂的研究进展

Progress in Research of Amorphous Alloy Catalyst

综述了采用化学还原法和浸渍还原法制备的非晶态合金催化剂(特别是N i-B非晶态合金催化剂)的最新研究进展。根据催化剂的形式,将非晶态合金催化剂分为纳米非晶态合金催化剂、负载型非晶态合金催化剂和特殊形貌的非晶态合金催化剂,对这3种催化剂分别进行了介绍。对非晶态合金催化剂未来可能的研究方向进行了分析和展望。

Amorphous alloy catalysts are considered as a new generation of metallic catalysts. In this paper, progress in research of nanosized, supported and specially structured amorphous alloy catalysts prepared by chemical reduction and impregnation reduction was reviewed, emphasizing on Ni -B amorphous alloy catalysts. The knowledge about Ni - B amorphous alloy catalysts provides basis for interpretation of physicochemical properties and catalytic behaviors of other amorphous alloy catalysts. However, it should be pointed out that only limited new preparation methods, novel supports and reactions have been exploited for amorphous alloy catalysts so far. A more comprehensive and in - depth work in this realm will undoubtedly enrich the practice and theory of heterogeneous catalysis.
