在金属催化领域,近年来人们对于高分子保护金属胶体的研究表现出很大的兴趣。高分散、窄分布金属胶体的制备研究成为众多工作者努力的目标。这在沟通分子催化与凝聚相物质催化间的联系有着重要的理论意义和应用价值。人们作出了种种努力设法获得高分散、窄分布的金属胶体。如:Bradley等报导用金属蒸汽冷凝法,Schmid等用水溶性三苯膦磺酸钠小分子配位体作为稳定剂,Esumi等用在有机溶剂中热解金属化合物的方法,Toshima等利用表面活性剂形成胶束的方法,Nagy的工作也很相似。这些工作在一定程度上取得进展。
In the field of metal catalysis, in recent years, people have shown great interest in the study of polymer protective metal colloids. Preparation of highly dispersed and narrowly distributed metal colloids has become the goal of many workers. This has important theoretical significance and application value in the connection between the catalytic molecules of molecular communication and the material catalysis of condensed phase. Efforts have been made to find highly dispersed, narrowly distributed metal colloids. Such as: Bradley et al reported by metal vapor condensation method, Schmid and other water-soluble sodium triphenylphosphine sulfonate ligand as a stabilizer, Esumi, etc. used in organic solvents pyrolysis of metal compounds, Toshima and other surfactants The method of forming micelles, Nagy’s work is also very similar. To a certain extent, these efforts have made progress.
