报告摘要:

　　To obtain high catalytic performance, highly dispersing the catalytic nanoparticles, e.g. Ni and Ni3Al, on the support powder, is a key technique. Fluidized bed CVD, namely FBCVD, is a common CVD method to deposit nanoparticles on fluidized powders by ensuring the reactive gas-powder contact. However, the grain size of the fluidized powders is limited in FBCVD. In order to extend the grain size limitation of FBCVD, we developed novel rotary CVD (RCVD) for surface modifications of fine powders. In the present study, Ni nanoparticles were precipitated by RCVD on various powders. The effects of RCVD condition on the microstructure and catalytic activities of Ni catalyst were investigated.
