Biomass carbohydrates, the most abundant renewable resources available, currently are viewed as the only alternative carbon sources for the construction of chemicals and materials for human survival in the future. Biomass-derived sugars ——cellulose and hemicellulose can be transformed into a variety of platform chemicals, of which furfural from dehydration of pentoses, hydroxymethyl furfural (HMF), from dehydration of hexoses as well as succedent levulinic acid (LA) and γ-valerolactone (GVL) are attracting the most attention. Contrast to conventional homogeneous catalysis, heterogeneous catalysts have advantages of facile separation from products and recycling, permitting higher reaction temperature and shorter reaction time and so on, which accounts for their tremendous potential in fine chemicals, biofuels manufacture and large scale industrial application, and can be expected to be the groundbreaking solution of environment, energy and resource utilization. Herein, the paper starting with biomass-derived sugars, summarized the research development of heterogeneous catalysis on hydrolysis of sugars and their transformation to various platform chemicals containing furural, HMF, LA as well as GVL respectively. Finally, a prospect of the heterogeneous catalysis on the biomass transformation is envisaged which is expected to make a brief guidance for the readers.
