Significance Designing sustainable artificial photosynthetic systems is a long-standing goal. Photoactive nanomaterials have been used to drive the respiration of microorganisms to produce biofuels. However, this strategy fails to capitalize on the excellent photocatalytic properties of nanomaterials, and the reaction products are limited to those compatible with the microorganism’s metabolism. Here, we use extracellular electron transfer from electrogenic bacteria to directly fuel photocatalytic hydrogen evolution by nanocrystals. This system introduces a way to capitalize on the catalytic properties of nanomaterials by providing an alternative to high-concentration sacrificial reductants. Given the high tunability of nanocrystalline photocatalysts, this method promises a sustainable and flexible route to a variety of solar fuels in the future.
