Cobalt Co on Carbon

Colloidal carbon supported cobalt can be obtained by the impregnation-chemical reduction method. Colloidal carbon sphere (CCS) support is produced from hydrothermal treated glucose. Porous spheres had a 300 nm diameter where pore diameter and specific surface area were 5.7 nm and 20071 m g , respectively. Also metals had a nearly amorphous structure. Co layer was a uniform thin layer on CCS support. Maximum hydrogen production rate of 10.4 L min observed for the hydrolysis 

The catalytic activity of CoB can be enhanced when they are supported on oxides. CoB nanocatalyst was impregnated on TiO, Al Oj, CeO by incipient-wetness impregnation method. It was demonstrated that the type of support affected the hydrogen production rate. Catalytic activity increased
