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 modern 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.
