Over the past decade, increasing attention has been paid to the exploration of environmentalfriendlyand alternative resources to prepare basic chemicals for relieving the stress of fossil resourcesand environmental issues. Lactic acid (LA, 2-hydroxypropanoic acid), the biomass-derived platformmolecule, has been used intensively in food, pharmaceuticals, and cosmetics. Considering the fermentationmethod for lactic acid production possesses environmental impact and high-cost issues, chemocatalyticapproaches to manufacturing LA from biomass have attracted much attention due to higher selectivitiesand lower costs. This paper emphasizes a review on the state-of-the-art production of LA from triose,hexose, cellulose and other biomass over heterogeneous acidic and alkaline catalysts.
