Porous Hollow Fiber Nickel Electrodes for Effective Supply and Reduction of Carbon Dioxide to Methane through Microbial Electrosynthesis

Microbial electrochemical reduction of CO 2 gas to value‐added chemical products requires the development of an electrode architecture with a three‐phase interface for efficient mass transport. A hybrid bioinorganic system for CO 2 reduction to CH 4 is developed by coupling a new electrode architecture with enriched methanogenic community. The novel electrode design consists of porous nickel hollow fibers, which act as an inorganic...
