Boosted Sacrificial-Agent-Free Selective Photoreduction of CO to CHOH by Rhenium Atomically Dispersed on Indium Oxide.

Solar-energy-driven photoreduction of CO is promising in alleviating environment burden, but suffers from low efficiency and over-reliance on sacrificial agents. Herein, rhenium (Re) is atomically dispersed in InO to fabricate a 2Re-InO photocatalyst. In sacrificial-agent-free photoreduction of CO with HO, 2Re-InO shows a long-term stable efficiency which is enhanced by 3.
