Abstract

The invention relates to a novel electrode material, in particular to a preparation method and application of a Reticulated nitrogen doped carbon coated manganese dioxide modified carbon cloth electrode material. The electrode takes a carbon cloth as a base, Then MnO2 nanowires were grown on the surface of carbon cloth by three-electrode system electrodeposition, and polypyrrole was electrodeposited on the surface of MnO2 nanowires by three-electrode system electrodeposition. Finally, the carbon cloth electrode was carbonized at high temperature to obtain the carbon cloth electrode modified bynitrogen-doped carbon-coated manganese dioxide. The carbon cloth electrode can be used as an anode material of a microbial fuel cell of a cellulose hydrolysate.

Description

technical field [0001] The invention relates to a novel electrode material, in particular to a preparation method and application of a carbon cloth electrode material modified with nitrogen-doped carbon coated with manganese dioxide, and belongs to the technical field of electrode materials. Background technique [0002] In recent years, the research on microbial fuel cells (MFC) has continued to heat up, has received widespread attention, and has achieved many important results. MFC has a wide range of substrate sources, and some pure substances, such as glucose, sucrose, and cellulose, can be used to generate electricity through MFC devices. The research on using cellulose material or straw hydrolyzate as the substrate of microbial fuel cells is still in its infancy. Ren et al. used carboxymethyl cellulose and MN301 cellulose as substrates, and then added the cellulosic fermentation bacteria Clostridium cellulolyticum and the electrochemically active bacteria Geobacter su...
