Science Daily  August 3, 2022 Researchers in the UK developed a chemical process that converts sunlight, water and carbon dioxide into acetate and oxygen to produce high-value fuels and chemicals powered by renewable energy. As part of the process, they grew CO2-fixing acetogenic bacterium Sporomusa ovata on a scalable and cost-effective photocatalyst sheet consisting of a pair of particulate semiconductors. The system effectively produces acetate and oxygen using only sunlight, CO2 and H2O, achieving a solar-to-acetate conversion efficiency of 0.7% at ambient conditions (298 K, 1 atm). The photocatalyst sheet oxidizes water to O2 and provides electrons and hydrogen to S. ovata […]
