摘要:Combiningphotocatalyticreduction with organic synthetic oxidation in the same photocatalytic redox system can effectivelyutilize photoexcited electrons and holesfrom solar to chemical energy. Here,we stabilized0DAuclusterson the substrate surfaceof Znvacanciesmodified2DZnIn2S4(ZIS-V)nanosheetsbychemically bonding Au-S interaction, forming surfactant functionalized Au/ZIS-V photocatalyst, whichcannot only synergisticacceleratethe selective oxidation ofphenylcarbinol to value-added productscoupled with clean energy hydrogen production but also further drive photocatalyticCO2-to-CO conversion. An internal electric fieldofAu/ZIS-Vohmic junction and Zn vacanciessynchronouslypromote thephotoexcitedcharge carrier separationandtransfer to optimizedactive sites for redox reactions.Compared with CO2reduction in water and thepristineZnIn2S4,the reactionthermodynamicsandkineticsof CO2reduction over the Au/ZIS-V were simultaneously improved about 11.09 and 45.51 times, respectively.Moreover, the photocatalytic redox mechanisms were also profoundly studied by13CO2isotope tracing tests,in situ electron paramagneticresonance (in situ EPR), in situX-ray photoelectronspectroscopy (in situXPS),in situ diffusereflection infrared Fourier transform spectroscopy (in situ DRIFTS)anddensity functional theory (DFT) characterizations, etc.These results demonstrate the advantagesofvacancies coupled withmetalclustersinthesynergetic enhancementofphotocatalyticredoxperformance and have great potential applications in awide range of environments and energy.
