AB  - Upgrading of abundant cellulosic biomass to isosorbide can reduce the dependence on limited fossil resources and provide a sustainable way to produce isosorbide, utilized for polymers, medicine and health care product synthesis. This review comprehensively examines the key steps and catalytic systems involved in the conversion of cellulose to isosorbide. Initially, the reaction pathway from cellulose to isosorbide is elucidated, emphasizing three critical steps: cellulose hydrolysis, glucose hydrogenation, and the two-step dehydration of sorbitol to produce isosorbide. Additionally, the activation energy and acidic sites during cellulose hydrolysis, the impact of metal particle size and catalyst support on hydrogenation, and the effects of catalyst acidity, pore structure, and reaction conditions on sorbitol dehydration have been thoroughly examined. Finally, the progress made in cellulose conversion to isosorbide is summarized, current challenges are highlighted, and future development trends are projected in this review.
