ABSTRACT
A highly dispersed Au and Pt catalyst supported on WOx was developed for high performance in the selective hydrogenolysis of glycerol to 1,3-propanediol (1,3-PD) under very mild reaction conditions (81.4 % glycerol conversion, 51.6 % 1,3-PD selectivity at 413â
K, 1â
MPa H2 ). The highly dispersed Au decreased the original surface Lewis-acid sites on Pt/WOx but greatly increased its inâ
situ generated Brønsted-acid sites with the assistance of H2 through the formation of frustrated Lewis pairs. These inâ
situ formed and spatially separated pairs of H+ and H- function as the active sites in glycerol conversion to 1,3-PD.
