AI Technical Summary
Existing photocatalysts suffer from poor thermodynamic stability and low quantum efficiency in photocatalytic CO2 conversion reactions. They cannot effectively utilize near-infrared light, and the rapid recombination of photogenerated electrons and holes leads to low conversion efficiency and poor selectivity of the target product.
A method for preparing ordered ultrathin Cs0.33WO3 nanosheets was adopted. Using WO3·0.33H2O nanosheets and CsOH·H2O as raw materials, ordered ultrathin Cs0.33WO3 nanosheets with excellent photocatalytic performance were prepared by high-temperature calcination and used for photocatalytic CO2 conversion.
Under full-spectrum, visible, and near-infrared light irradiation, ordered ultrathin Cs0.33WO3 nanosheets exhibit excellent photocatalytic CO2 conversion performance, providing a large number of active sites and optimizing the electronic structure, thereby improving the separation and transfer efficiency of photogenerated carriers.
