Abstract：In order to reduce the consumption of palladium, platinum, gold and other precious metals, improve the situation of environmental pollution and energy crisis, the preparation and modification methods of biomass based single-atom catalysts were reviewed, including pyrolysis, wet chemistry, electrochemical deposition, in situ synthesis, biomass compound method, etc. Based on the characteristics of homogeneous dispersion, high surface area, catalytic activity and selectivity of biomass based single-atom catalysts, the application of biomass based single-atom catalysts in wastewater treatment, carbon dioxide reduction, organic chemical synthesis, oxygen reduction reaction and other fields was introduced. It is pointed out that biomass-based single-atom catalysts are functional materials with high efficiency, environmental protection and low cost. The future research should be focus on developing more effective and controllable preparation methods of biomass-based single-atom catalysts, and promoting the industrialization application of biomass-based single-atom catalysts by reducing the preparation cost and improving the process conditions.
