Description
Summary:This study presents a detailed examination of Ni-CeO2/ZSM-5 catalysts synthesized via the impregnation method for the hydrogenation of D-glucose, with a sharp focus on the transformative role of ceria. Notably, the incorporation of ceria significantly reduced the nickel crystallite size and effectively prevented nickel leaching, a critical advancement compared to ceria-free catalysts. Despite the varying ceria content, the catalytic efficiency for converting D-glucose to sorbitol remained remarkably stable, highlighting the robustness of the catalyst design. The investigation also evaluated the effect of reaction temperature, revealing that higher temperatures enhanced glucose conversion while adversely affecting sorbitol selectivity and yield. Sorbitol was the dominant hydrogenation product, with fructose and mannitol also generated as key by-products. The Ni-0.14CeO2/ZSM-5 catalyst showed the best performance, achieving a remarkable glucose conversion of 79 % and a sorbitol selectivity of 75 % under challenging conditions (140 °C, 40 bar H2, and reaction time of 2 h). This breakthrough identifies Ni-0.14CeO2/ZSM-5 as a highly promising and selective catalyst for efficient sorbitol production, offering significant implications for industrial applications.
