Abstract

The invention discloses a preparation method and application of a ginger-derived N-doped three-dimensional independent biomass carbon material, belongs to the technical field of inorganic materials, and relates to a preparation method and application of a biomass carbon material. The invention aims to solve the problems of poor performance and efficiency of a microbial fuel cell due to high electron transfer resistance and low power density when a biomass-derived carbon material prepared by the existing method is used as an anode of the microbial fuel cell. The method comprises the following steps: firstly, drying the fresh ginger, then heating to 800-1200 DEG C, and finally calcining in a nitrogen atmosphere at the temperature of 800-1200 DEG C. The N-doped three-dimensional independent biomass carbon material derived from ginger is applied as a microbial fuel cell anode. The biomass carbon material has good biocompatibility, can be quickly started and has good charge transfer capacity, and the porous structure of the biomass carbon material allows effective ion transport and microbial community succession and is beneficial to long-term operation.

Description

technical field [0001] The invention belongs to the technical field of inorganic materials, and relates to a preparation method and application of a biomass carbon material. Background technique [0002] Microbial fuel cells (MFCs) are promising clean energy sources that can utilize microorganisms as catalysts to directly convert waste chemicals into electricity for simultaneous waste treatment and energy regeneration. Electroactive microorganisms in MFCs generate electrons, electrons through metabolism. There are two main modes of delivery, either direct electron transfer (DET) through outer membrane c-type cytochromes (OMc-cyts) and conducting nanowires, or mediated electron transfer (satisfaction) through autocrine redox mediators such as flavins. Geobacteria can utilize auto-secreted flavins as redox cofactors in OMc-Cyts, thereby facilitating electron transfer, and some studies have improved electrochemical performance through the selection and modification of anode mat...
