摘要
纳米材料具有独特的晶体结构及表面特性 ,其催化活性和选择性大大高于传统催化剂 ,目前已经被国内外作为第 4代催化剂进行研究和开发 .介绍了纳米材料的催化特性 ,综述了纳米金属粒子催化剂、纳米金属氧化物催化剂、纳米半导体粒子、纳米固载杂多酸催化剂、纳米(复合 )固体超酸催化剂、磁性纳米固体酸催化剂、碳纳米管及分子筛等的应用进展 .
Nanometer catalysts have much greater catalytic activity and selectivity than those of traditional catalysts because of their unique crystallographic structure and surface properties,and have been developed as catalyst of the 4th generation at home and abroad.Catalytic properties of nanometer materials are introduced and application of nanometer metal cluster catalysts,nanometer oxide catalysts,semiconductor nanometer materials,supported nanoheteropolyacid salts catalyst,nanosolid superacid catalysts,magnetic nanosohid acid catalysts,carbon nanotube and molecular sieves are reviewed.Advantages of nanometer catalysts and problems exist in its application are discussed.
