Biorecovery of Precious Metals from Wastes and Conversion into Fuel Cell Catalyst for Electricity Production
Copyright policy )Biorecovery of Precious Metals from Wastes and Conversion into Fuel Cell Catalyst for Electricity Production
Bio-manufacturing of nano-scale palladium was achieved using bacterial cells. Highly active Pd-catalyst (Bio-Pd) produced by an E. coli mutant gave power output in a fuel cell. Up to ~115% of the maximum power generation was achieved by electrodes of Bio-Pd catalysts from Escherichia coli, compared to that from a commercial-Pd electrode (~0.099 W). A bio-precious-metals (Bio-PM) catalyst made directly from an industrial reprocessing solution by the E. coli was also made into fuel cell electrodes and ~0.06W of maximum power generation was observed.
