Photocatalysis of glycerol over Pt/TiO2 catalyst

Glycerol is produced as waste by-product in solution form during the transesterification process and potentially detrimental to the environment. Hence, photocatalysis was employed in the current work for the treatment of glycerol waste using UV light activated Pt/TiO2 photocatalyst. The reaction was...
