	The C-O hydrogenolysis of erythritol was investigated using Pt/W/Ti-SBA-15 catalysts (4 wt\% Pt, 1 wt\% W and Si/Ti molar ratio = 50, 33, 20 and 10). Ti-incorporation enhanced the hydrogenolysis activity and the yield of 1,4-butanediol (1,4-BDO). A catalyst with Si/Ti = 20 afforded erythritol conversion of 94 mol\% with 1,4-BDO yield of 32.6 mol\% and total BDOs yield of 51.7 mol\% at 190 degrees C, 50 bar H2 and 12 h. For the catalyst with no titanium (Pt/W/SBA-15), a double the time was required to achieve such yield. There observed electronic connectivity amongst Ti, Pt and W. For the catalyst with Si/Ti = 20, a greater amount of interfacial Pt-O-W(Ti) sites with Pt in + 2 oxidation state was present. The enhanced catalytic performance of these catalysts was corresponded to dispersed Pt (that facilitate hydrogen activation and spillover) and acidic interfacial Pt-O-W sites (that promote the adsorption and hydrogenolysis of erythritol to diols).</p>

	In this study, we investigated the conversion of sucrose to 1,2-propanediol (1,2-PDO) using various Cu-La metals supported on activated carbon (AC), a versatile support known for its hydrophobicity and high surface area. Among the catalysts tested, 6\% Cu-20\% La/AC demonstrated the highest activity, achieving a 72\% yield of 1,2-PDO under optimal reaction conditions of 200 degrees C, 40 bar H2, and 6-h reaction time. Comparative studies using cellulose, sucrose, glucose, and fructose as substrates identified sucrose as the most favorable feedstock for 1,2-PDO production. Detailed catalyst characterization (XRD, TEM, FE-SEM, TPR, TPD, XPS) revealed that the high dispersion, presence of metallic copper, and synergy between Cu and La, along with the presence of optimal acidic and basic sites, were responsible for the catalyst{\textquoteright}s high selectivity of 1,2-PDO. Additionally, the effect of different supports, including HY, NaY, HZSM-5, NaZSM-5, gamma-Al2O3, and AC, on sucrose conversion was examined, with AC showing superior performance. The catalyst{\textquoteright}s reusability was also assessed.Graphical abstractInvestigation of Cu-La metals supported on activated carbon for the catalytic conversion of sucrose to 1,2-propanediol, with an emphasis on choice of support, feedstock selection, catalyst performance, and stability under optimized reaction conditions.</p>
