Abstract：

Adsorption　and　activation　of　C–H　bonds　by　photocatalysts　are　crucial　for　the　efficient　conversion　of　C–H　bonds　to　produce　high-value　chemicals.　Nevertheless,　the　delivery　of　surface-active　oxygen　species　for　C–H　bond　oxygenation　inevitably　needs　to　overcome　obstacles　due　to　the　separated　active　centers,　which　suppresses　the　catalytic　efficiency.　Herein,　Ni　dopants　are　introduced　into　a　monolayer　Bi2WO6　to　create　cascaded　active　units　consisting　of　unsaturated　W　atoms　and　Bi/O　frustrated　Lewis　pairs.　Experimental　characterizations　and　density　functional　theory　calculations　reveal　that　these　special　sites　can　establish　an　efficient　and　controllable　C–H　bond　oxidation　process.　The　activated　oxygen　species　on　unsaturated　W　are　readily　transferred　to　the　Bi/O　sites　for　C–H　bond　oxygenation.　The　catalyst　with　a　Ni　mass　fraction　of　1.8%　exhibits　excellent　toluene　conversion　rates　and　high　selectivity　towards　benzaldehyde.　This　study　presents　a　fascinating　strategy　for　toluene　oxidation　through　the　design　of　efficient　cascaded　active　units.　©　The　Author(s)　2024.
