| Abstract: | Nanostructured NiCe particles were prepared by H 2 are plasma method,and the catalytic property of nono NiCe particles in gas phase hydrogenation of benzene was studied.The results showed that the catelytic activity of nano NiCe particles was related to both hydrogen storage property and the existence of NiCe alloys in the surface of nano NiCe particles.The fact that nano NiCe particles possessed high catalytic selectivity and thermal stability was attributed to the special structure of nano particles and the addition of rare earth cerium. |
