Catalytic conversion of sucrose to 1,2-propanediol over alumina-supported Ni–Mo bimetallic catalysts

Abstract

The metal combination of 8%Ni–20%Mo/γ-Al2O3 is found to be effective in producing a good yield of 1,2-propanediol (∼74%) under mild reaction conditions of 180 °C, 40 bar H2 pressure at a run time of 4.5 h in a batch reaction.

Enhanced Catalytic Conversion of Disaccharides to Propylene Glycol Using Metal-Supported Graphitic Carbon Nitride

“…Our previous study reported ∼74% 1,2-PD yield using 8%Ni-20%Mo/γ-Al 2 O 3 under the reaction conditions of 180 °C, 40 bar H 2 pressure, and 4.5 h reaction time. This report reveals that the combination of Ni–Mo and tuned acidity and basicity helps obtain 1,2-PD selectively under milder reaction conditions.…”

“…19 The main reaction pathway for sucrose hydrogenolysis is depicted in Scheme 1 based on the literature. 17,18 The pathway provided illustrates the reactions in converting sucrose to various products. Initially, sucrose undergoes hydrolysis to produce glucose and fructose.…”

“…The 1,2-PD yield of 74% and complete conversion of sucrose were achieved at mild reaction conditions (180 °C and 40 bar H 2 ). 17 Later, Shen et al, using the functionalized Pt/deAl-β@Mg(OH) 2 catalyst, selectively synthesized 1,2-PD up to 33% yield. 18 Recently, our research team conducted a comprehensive investigation into the impact of incorporating Ni−Ce metal combinations with titania support in sucrose hydrogenolysis.…”

“…In 2022, our group first reported the catalytic conversion of sucrose to 1,2-PD using Ni–Mo-supported alumina. The 1,2-PD yield of 74% and complete conversion of sucrose were achieved at mild reaction conditions (180 °C and 40 bar H 2 ) . Later, Shen et al, using the functionalized Pt/deAl-β@Mg­(OH) 2 catalyst, selectively synthesized 1,2-PD up to 33% yield .…”

Coupling of PET waste electroreforming with green hydrogen generation using bifunctional catalyst

“…7,8 Therefore, replacing water oxidation with a new oxidation reaction to reduce energy consumption and to produce higher value product (than oxygen) is attracting ever-increasing interest. 9,10 Electrooxidation of many different organic molecules has been reported to couple with HER for green H 2 generation, such as biomass, [11][12][13] hydrazine, 14,15 isopropanol, 16 benzylamine, 17 urea, 18 formic acid, 19 and so on.…”
