摘要

Abstract

Ru and Mo bimetallic catalysts supported on active carbon modified by phosphotungstic acid (PW) were designed and applied in glycerol hydrogenolysis reaction. The physicochemical properties of the catalysts were characterized and the presence of active sites was investigated from the perspective of the glycerol hydrogenolysis performance. The MoO

is highly selective for the C—O bond cleavage of glycerol molecules

which can reasonably regulate the strong C—C bond cleavage activity of Ru nanoparticles. By using sequential deposition of Ru and Mo supported on mesoporous PW-C

the characterization results show that the combination of isolated low-valence MoO

with metal Ru particles can form “MoO

-Ru-PW”

which provides highly catalytic activity toward C—O bond cleavage

selectively producing more C3 alcohols (mainly 1

2(3)-propanediol). The glycerol conversion of 1% Mo/Ru/PW-C catalyst was 59.6%

the selectivity of C3 alcohol was 96.1%

and the selectivity of propanediol (1

2(3)-propanediol) was 94.9%. It is noteworthy that the selectivity of 1

3-propanediol reached 20.7% when the PW was 21.07% (mass). This study provides experimental

evidence for the tandem dehydration and hydrogenation mechanism of the multifunctional Mo/Ru/PW-C catalyst.
