A　nickel　titanate　(NTO)　photocatalyst　has　been　developed　for　the　oxygen　evolution　reaction　(OER)　with　an　exceptionally　broad　light　wavelength　excitation　ranging　from　visible　to　infrared.　Specifically,　by　loading　CoOx　as　the　co-catalyst,　the　apparent　quantum　yields　for　the　OER　were　ca.　2.2%,　1.0%,　and　0.8%　at　wavelengths　of　470,　760,　and　850　nm,　respectively.　The　achievements　reveal　that　the　NTO　photocatalyst　is　highly　efficient　even　under　illumination　with　near-infrared　(NIR)　light,　which　confers　the　potential　for　highly　efficient　solar-driven　oxidation　reactions.　©　2023　The　Royal　Society　of　Chemistry.
