Photoelectrochemical syngas production from aqueous CO2 is a promising technique for carbon capture and utilization. Herein, we demonstrate the efficient and tunable syngas production by integrating a single‐atom cobalt‐catalyst‐decorated α‐Fe2O3 photoanode with a bimetallic Ag/Pd alloy cathode. A record syngas production activity of 81.9 μmol cm−2 h−1 (CO/H2 ratio: ≈1 : 1) was achieved under artificial...

An Ar atmospheric treatment is rationally used to etch and activate hematite nanoflakes (NFs) as photoanodes toward enhanced photoelectrochemical water oxidation. The formation of a highly ordered hematite nanorods (NRs) array containing a high density of oxygen vacancy is successfully prepared through in situ reduction of NFs in Ar atmosphere. Furthermore, a hematite (104) plane and an iron suboxide...
