[Display omitted] •Biomass carbon was prepared from Mango wood.•Biomass carbon C/1050 with large electrochemical area was developed.•C/1050 could be used as a quality anode material in MFC.•Mango wood could be utilized as high value-added materials. Microbial fuel cell is a green and sustainable bio-electrochemical system that can harvest bioelectricity from organic matter conversion by bacteria in wastewater, but weak electrochemical activity and poor biocompatibility between electro-active bacteria and anode limit its scale-up application. In the present, the biomass carbon derived from mango wood was prepared via one-step carbonization method for anode materials in microbial fuel cell. A desirable anode C/1050 with large electrochemical active surface area (75.3 cm2), low electron transfer resistance (4.36 Ω), and benign biocompatibility were developed, achieving power density up to 589.8 mW·m−2. This study provides a low-cost and high-performance biomass carbon used as anode material in microbial fuel cell for practical application.
