A Living Semiartificial Photoelectrocatalytic Biohybrid for Solar CO₂ Fixation and Fermentation to Fatty Acids.

ABSTRACT: To address the global climate and energy crisis, innovative strategies are urgently needed to transform CO₂ into sustainable fuels and chemicals. We present a semiartificial biophotoelectrochemical (BPEC) platform, combining solar energy conversion with naturally evolved microbes to develop solutions for transforming CO₂ and water into multicarbon products─without sacrificial additives or precious materials. This remains extremely challenging for fully artificial photocatalytic systems. Our system features a scalable and low-cost CuBi₂O₄ photocathode, stabilized by a thin MgO interlayer, in direct contact with the CO₂-fixing bacterium Sporomusa ovata grown on the electrode surface. This interface enables direct electron uptake,
