Catalytic Conversion of Glycerol to Glycerol Carbonate Utilizing CO₂ and Dimethyl Carbonate
… conversion of glycerol to value-added glycerol carbonate using CO2, an abundant, non-toxic greenhouse gas, and dimethyl carbonate (DMC), which yields more glycerol carbonate. The catalysts were prepared by co-precipitation method, and characterized by using XPS, FT-IR, XRD, TGA, SEM, and CO2-TPD …
