Abstract
Microbial Electrosynthesis(MES)is a technology that uses electroactive microorganisms to take up extracellular electrons to convert CO2 or organic wastes into renewable chemicals.In this paper,the electrode modification approach is firstly described,and it is pointed out that carbon-based materials,with their diverse morphology,excellent chemical stability and high specific surface area,play an important role in electrode modification,and their mechanism of action is mainly through providing more microbial attachment points and enhancing the electron transfer efficiency.While non-carbon based materials,such as metallic materials,are widely used to enhance electrode performance due to their excellent electrical conductivity and catalytic activi-ty,and their mechanism of action lies in accelerating the catalytic reaction on the electrode and promoting the generation of specific products.Secondly,from the perspective of electroactive microorganisms,the article re-veals that the common point on the modification of electrode materials and microbial cell modification is to en-hance the microbial electron transfer ability,and the difference is that the microbial cell modification can di-rectly act on the physiological and genetic characteristics of microorganisms in order to enhance the electron transfer ability and the efficiency of substrate conversion.In addition,the article analyses the relationship be-tween nanomaterials and high value-added products,and concludes that the rational selection and design of e-lectrode materials and microbial cell modification strategies are crucial for improving the efficiency and product selectivity of MES systems.Finally,it provides an outlook on the challenges and future research directions of MES technology.关键词
