• The increase in greenhouse gas emissions due to high consumption of fossil fuels is one of the key contributors to climate change. Conversion of biomass into valuable chemicals via hydrogenolysis reaction is regarded as an alternative approach to address this matter, particularly through catalytic hydrogenolysis of sorbitol. Unfortunately, the deactivation of the catalyst has limited its industrial application. Therefore, new compelling catalysts that may enhance the performance of hydrogenolysis reaction has garnered considerable interest. Ruthenium-based catalyst has a high potential as it demonstrated high catalytic activity in most studies. The effect of metal (monometallic and bimetallic), supporting material and acid/base properties have significant effects on catalytic performance. This review is an attempt to provide a recent summary on the sorbitol hydrogenolysis over heterogeneous catalysts, involving the aspects of the catalysts, reaction mechanism and deactivation, as well as future opportunities on the studies.
