用化学沉积法制备了非晶态催化剂Ni-P-SiO2测定了催化剂对苯乙烯加氢的活性, 并与相应的晶态Ni-P-SiO2及Ni-SiO2的活性对比。结果表明, 还原态的Ni是反应的活性中心。用高真空TPD-MS研究了该催化剂对氢、一氧化碳的吸附, 提出了一氧化碳加氢的反应机理。

The catalytic activities of amorphous Ni-P-SiO2 and crystallization Ni-P-SiO2 and Ni-SiO2 were compared in the hydrogenation of styrene. Reduced Ni was shown to be the active site. The chemisorption and interaction of H2 and CO on these catalysts were examined, and a mechanism was proposed for the hydrogenation of CO.
