Semiconductive photocatalysts that efficiently absorb solar energy could help reduce the energy required to drive a bioelectrochemical process that converts CO2 emissions into valuable chemicals, KAUST researchers have shown.
Recycling CO2 could simultaneously reduce carbon emissions into the atmosphere while generating useful chemicals and fuels, explains Bin Bian, a Ph.D. student in Pascal Saikaly’s lab, who led the research. “Microbial electrosynthesis (MES), coupled with a renewable energy supply, could be one such technology,” Bian says.
