Photocatalytic Reduction of CO 2 with H 2 O Mediated by Ce-Tailored Bismuth Oxybromide Surface Frustrated Lewis Pairs

Photocatalytic reduction of CO2 into available organic compounds has received remarkable attention. However, photocatalytic CO2 reduction is limited to meet industrial application requirements because of the lack of effective photocatalysts. Surface frustrated Lewis pairs (FLP) are found in bismuth oxybromide (BiOBr), which are effective catalytic sites to activate and photocatalytically reduce CO2. Furthermore, the introduction of Ce4+ and oxygen vacancy can optimize both the electronic state and the FLP property of BiOBr. The combined experimental and theoretical characterizations reveal that Ce4+ and O2– can form the frustrated Lewis acid–base pairs, which can catch, excite, and reduce CO2 into CO at a high…
