The nanometer autonomous vehicle assembly MoNiP hydrogenation catalysts were prepared by homogeneous precipitation using thiourea as precipitant matrix and citric acid as complexing agen. The catalysts were characterized by BET, NH3TPD, FTIR spectra of CO adsorbed and XPS. The results of BET and FTIR spectra of CO showed that when the content of thiourea was 40%, catalytic performance of the catalyst was best. The homogeneous precipitation catalyst achieved the desulfurization rate of 95.3% which was higher than the reference catalyst by 1.7%.
