Abstract

Highlights: [•] Addition of SiO2 to PtW/Zr greatly enhanced activity and 1,3-propanediol selectivity. [•] 54.3% conversion and 52.0% 1,3-propanediol selectivity were achieved over 5PtW/ZrSi. [•] A model scheme of WO x transformation due to SiO2 doping has been built. [•] Pt and polytungstate have been identified as the dominant active phases. [•] Glycerol hydrogenolysis conforms to the dehydration–hydrogenation mechanism. [Copyright &y& Elsevier]

Abstract

Highlights: [•] B2O3 can promote the dispersion of copper species and stabilize copper particles. [•] Addition of B2O3 to Cu/SiO2 greatly enhanced activity and stability. [•] 100% Conversion and 98.0% 1,2-propanediol selectivity were achieved over 3CuB/SiO2. [•] 1,2-Propanediol yield was proportional to Cu specific surface area. [•] Glycerol hydrogenolysis is a structure-sensitive reaction. [ABSTRACT FROM AUTHOR]
