“…MgOy enhances acidic and basic sites in novel Pt-WOx-MgOy and improves the catalytic performance of glucose selectively to diols. 13 Sucrose is widely available in nature, since it is available in high quantities in sugar cane, sugar beets, and other plants. As a result, it is a more abundant yet economical feedstock than glucose, which is normally produced from maize or another source.…”

Propylene glycol (or) 1,2-propanediol (1,2-PD) is an important polyol widely used for pharmaceuticals, polyester resins, paints, cosmetics, antifreeze, etc. Sucrose has emerged as a promising feedstock to produce 1,2-PD, as indicated by recent research findings. Graphitic carbon nitride (g-C 3 N 4 /gCN) was synthesized by using different crucibles. Ni−Mo was loaded on different g-C 3 N 4 supports via the wetness impregnation method for sucrose hydrogenolysis. Effects of different g-C 3 N 4 supports were studied. Catalysts with varying Ni (x = 0−8 wt %) and Mo (y = 0− 15 wt %) contents were characterized using XRD, BET, XPS, FE-SEM, Py-FTIR, HR-TEM, TPD (CO 2 )and Raman spectroscopy. An attempt was made on sucrose conversion into 1,2-PD using a Ni−Mo/g-C 3 N 4 catalyst. The catalyst containing 8% Ni and 10% Mo on Gr-gCN exhibited the best performance, achieving complete sucrose conversion with a 76% yield of 1,2-PD under mild reaction conditions. The presence of highly dispersed nanoparticles and the nature of graphitic carbon nitride help improve the reactions' yield by allowing reactions at lower temperatures, reducing the occurrence of side reactions, and increasing recycling rates. A straightforward approach to material preparation, coupled with the exceptional dispersion of metal nanoparticles, paves the way for a novel platform for biomass conversion.

“…In the transformation of biomass-derived polyols, humin formation from side reactions, which is liable to occur during C6 sugar alcohols hydrogenolysis, is a serious problem because high-temperature reactions are required for the hydrogenolysis of C-O bonds due to the strong bond even with noble metals. 44,45 Moreover, the selective transformation of polyols such as sorbitol and glucose to diols and triols is difficult because polyols have many OH groups with similar reactivities in the flexible alkyl chain. In contrast, isosorbide has two different functional groups, two secondary OH groups and four ether bonds in the rigid structure, and the reactivity difference of these functional groups can be used for the selective transformation.…”
