Abstract:

A series of CePO4-Ni3P and Ni3P catalysts with various Ce/Ni molar ratio were prepared by in-situ H2 temperature-programmed reduction, and utilized to catalyze the transfer hydrogenation of phenol. The effects of Ce/Ni molar ratio, hydrogen donors, reaction temperature and reaction time on the catalytic perfor-mance were investigated. What’s more, the reaction kinetic parameters were calculated. The reaction results showed that the addition of CePO4 could significantly improve the phenol conversion. The promoting effect was the most obvious when the Ce/Ni molar ratio was 0.2. 2-Propanol exhibited the best catalytic activity among all the screened solvents. A high cyclohexanol selectivity of 92.0% and phenol conversion of 93.1% could be obtained at 220 ℃ for 6 h over the CePO4(0.2)-Ni3P catalyst using 2-propanol as the hydrogen donor and solvent.

Key words: Ni3P, CePO4, Transfer hydrogenation, Phenol, 2-Propanol
