Question

Please give the mechanism of hydrogenation of cinnamaldehyde in presence of nickel as catalyst.

Answer 1

A series of SiO2 supported transition metal (Fe, Co, Ni, Mo and W) phosphide catalysts were synthesized and tested for the selective hydrogenation of cinnamaldehyde (CMA). Among these tested catalysts, Ni12P5/SiO2 and Ni2P/SiO2 prepared with initial Ni/P ratios of 2/1.3 and 1/1 exhibited high activity and selectivity for the conversion of CMA to hydrocinnamaldehyde (HCMA)
