Research initiatives in MAPTech Lab have led to groundbreaking microbial electrosynthesis advances. Our team developed a reactor using stackable, cylindrical porous nickel fibers to deliver CO₂ and electrons directly to chemolithoautotroph microbes, converting CO₂ into methane with 77% efficiency -compared to just 3% in conventional flat-sheet designs- and producing acetate, with yields nearly doubling after coating the fibers with carbon nanotubes that enhanced CO₂ adsorption 11-fold. “The microbes obtain their energy from the oxidation of inorganic compounds, such as hydrogen, iron and sulfur,” explains Bin Bian. Ongoing work focuses on scalable fiber fabrication and exploring renewable energy-powered MES.
