双金属纳米材料与催化

双金属纳米材料作为工业上少见的一类催化剂材料,在合成过程中可通过对其组成、结构晶粒大小尺寸的调控,实现其催化性能的合理调控,因此,近年来备受催化材料化学领域科技工作者的广泛关注.随着纳米材料调控合成方面的技术进步,具有均一小尺寸可控结构的纳米材料对于制备高效催化剂材料和研究催化反应机理具有重要的意义.结合纳米技术探索开发设计新型的双金属纳米催化剂材料颇具挑战性.本文围绕双金属纳米催化剂的合成、结构及其相关催化性能,从不同的双金属纳米催化剂出发,对催化剂的性能提高、催化机理研究的若干问题和分析手段及方法在催化研究中的进展发表一点初浅认识.

Bimetal catalytic nanomaterials

As one kind of unusual catalytic materials in the industrial catalysis community, the bimetal materials have attracted considerable attentions due to the controlled composition, size and nanostruture of crystals and their promising reasonable controlled catalytic activity in the catalytic reaction. In recent years, the controlled preparation of different kinds of nanomaterials has achieved rapid progress, these nanomaterials with little size and controlled structures are very significant to improve the catalytic activity and study the catalytic mechanism. It is a challenge to design and develop more efficient bimetal catalytic materials with the help of modem nanotechnology. In this review, we discussed the bimetal nanomaterials catalytic activity in kinds of catalytic reaction, and the influence factors of the catalytic activity of these bimetallic nanomaterials in the recent catalytic research progress. Some new promising characterization and research methods were also discussed in the end of the review.
