超微粒子以共各方面独特的性质受到了科学家的注视,它在催化中的应用更为催化工作者展示了一个趣味盎然、富有活力的研究领域。从目前这一领域的研究可以看到,超微粒子对催化氧化、还原和裂解反应都具有很高的活性和选择性,对光解水制氢和一些有机合成反应也有明显的光催化活性。国际上已把超微粒子催化剂称为第四代催化剂,在重要 Ultrafine particles have attracted the attention of scientists for their unique properties in all aspects. Their application in catalysis has also catalyzed the demonstration of a dynamic and energetic field of research. From the current research in this field, it can be seen that ultrafine particles have high activity and selectivity for catalytic oxidation, reduction and cleavage reactions and also have obvious photocatalytic activity for hydrogen production from photolysis to water and some organic synthesis reactions. It is important that the ultrafine particle catalyst is called the fourth generation catalyst internationally
