Solar-driven selective conversion of millimolar dissolved carbon to fuels with molecular flux generation.

ABSTRACT: The direct utilization of dissolved inorganic carbon in seawater for CO₂ conversion promises chemical production on-demand and with zero carbon footprint. Photoelectrochemical (PEC) CO₂ reduction (CO₂R) devices promise the sustainable conversion of dissolved carbon in seawater to carbon products using sunlight as the only energy input. However, the diffusion-dominant transport mechanism and the near-zero concentration of CO₂(aq) (CO₂ dissolved in aqueous solution) in static seawater has made it extremely challenging to achieve high solar-to-fuel (STF) efficiency and high carbon-product selectivity. Here, where CO₂(aq) as a reactant generated in situ by acidification of HCO₃^- flows continuously from BiVO
