Abstract

The invention discloses a preparation method of a porous carbon bioelectrode. The steps are as follows: adding phloroglucinol and 5-hydroxymethylfurfural into a solution and mixing them evenly; after stirring, adding a catalyst to carry out solution prepolymerization; Put the pre-polymerization solution into a mortar, add dodecane drop by drop, and emulsify at the same time; place the emulsified viscous emulsion at 120-150°C for 20-30h, then extract and wash with ethanol, and put it in an oven Dry, then place at 750°C for 4‑5h, and cool down to room temperature for porous carbon bioelectrodes. The invention uses phloroglucinol and 5-hydroxymethylfurfural as raw materials to prepare a porous carbon bioelectrode, the carbonization process is simple and easy to operate, green and environmentally friendly, and has no corrosion to production equipment.

Description

technical field [0001] The invention belongs to the technical field of porous carbon materials, and in particular relates to a preparation method of a porous carbon bioelectrode. Background technique [0002] Since entering the 21st century, my country's economy has developed rapidly and people's living standards have gradually improved. Problems, especially water pollution, have become prominent factors restricting my country's economic and social development. [0003] Microbial fuel cell (MFC for short) technology uses microorganisms as catalysts to oxidize organic or inorganic substances in wastewater to generate electricity. With the dual characteristics of treating waste water and generating electricity, it can provide a continuous energy source for resource recycling. [0004] However, the current difficulties faced by microbial fuel cells are low power generation performance and short continuous operation time. They are still in the laboratory research stage, and the...
