1. A method of making a hydrogenation catalyst, the method comprising:

dispersing Ni in a mesoporous SiO2 to form a Ni@meso-SiO2 composite;

contacting the Ni@meso-SiO2 composite with a P source to provide a Ni_xP_y@meso-SiO2 composite, wherein contact between the Ni@meso-SiO2 composite and the P source occurs as a temperature between 225° C. and 375° C., and wherein the Ni_xP_y@meso-SiO₂composite includes Ni_xP_ynanoparticles that are less than 5 nm in size and are embedded within the mesoporous SiO₂.
