Assembling a S-type heterostructure photocatalyst of Bi12O17Cl2/CuBi2O4 to reduce CO2 into CO
Source abstract
Abstract
The CO 2 photocatalytic reduction is an essential strategy to meet with the carbon-neutral cycle. This investigation presents the successful preparation of a CuBi 2O 4/Bi 12O 17Cl 2 (CuBO/UBOCl) composite for CO 2 photocatalytic reduction, forming a series S-type heterostructures where CuBO rectangle plates tile on UBOCl nano-belts. The optimal CuBO/UBOCl-50 % achieved significant CO 2 reduction to CO (231.84 μmol·g −1) within 3 hours of simulated sunlight irradiation, with dramatically improved stability. Mechanistically, CuBO`s narrowed band gap enables efficient solar energy absorption, while UBOCl`s abundant anion defects facilitate CO 2 trapping, enhancing photocatalytic performance. Furthermore, the formation of a S-type heterostructure can best separate photo-carriers and maintain strong redox capacity. In conclusion, this investigation proposes a novel approach for developing solar-driven photocatalysts for effective CO 2 conversion.
