| Abstract: | Ni3Si2O5（OH）4 microspheres have been synthesized by a hydrothermal method, and Ni/SiO2 catalysts with core- shell structure have been successfully fabricated by hydrogen reduction at 823K. The effects of reaction time, temperature and pressure for nitrobenzene liquid hydrogenation on Ni/SiO2 catalysts were investigated. The results indicate that the conversion of the nitrobenzene can reach to 97%, and the selectivity of the phenylamine can reach 99% at optimum conditions. |
