Highly efficient TiO₂-supported Co-Cu catalysts for conversion of glycerol to 1,2-propanediol.

ABSTRACT: Glycerol is a low-cost byproduct of the biodiesel manufacturing process, which can be used to synthesize various value-added chemicals. Among them, 1,2-propanediol (1,2-PDO) is of great interest because it can be used as an intermediate and additive in many applications. This work investigated the hydrogenolysis of glycerol to 1,2-PDO over Co-Cu bimetallic catalysts supported on TiO₂ (denoted as CoCu/TiO₂) in aqueous media. The catalysts were prepared using the co-impregnation method and their physicochemical properties were characterized using several techniques. The addition of appropriate Cu increased the glycerol conversion and the 1,2-PDO yield. The highest 1,2-PDO yield was achieved over a 15Co0.5Cu/TiO₂ catalyst at 69.5% (glycerol conversion of 95.2%
