摘要: Silica-supported NiCoP ternary phosphides formed from precursors with Ni/Co/P=1/1/1, 1/1/1.5, and 1/1/2 were prepared by temperature-programmed reduction. To prove the synergetic effect of NiCoP/SiO2 in hydrazine decomposition, Ni2P/SiO2 and CoP/SiO2 were prepared to compare with them. The samples were characterized by X-ray diffraction (XRD), and Fourier transform infrared (FTIR) analysis. The catalytic activities of hydrazine decomposition were measured in a fixed-bed continuous-flow micro reactor at atmospheric pressure, and followed the order NiCoP/SiO2 > CoP/SiO2 > Ni2P/SiO2. The NiCoP/SiO2 catalysts were found to exhibit different activities of hydrazine decomposition with the metal/P molar ratio of the oxide precursor having an optimal phosphorous content for the reaction. The FTIR results of CO adsorbed on NiCoP/SiO2, Ni2P/SiO2, and CoP/SiO2 catalysts testify to an electron transfer between the Ni and Co atoms in the NiCoP/SiO2.
