Аннотация:In this study, nitrogen doped carbon quantum dots (NLCQDs) were synthesized by hydrothermal method using alkaline lignin as the carbon source and ethylenediamine as the nitrogen source. Subsequently, a BiOCl/WO3 heterojunction was constructed through a solvothermal approach. By optimizing the molar mass ratio of BiOCl to WO3, BiOCl/WO3-2 composite (BiOCl: WO3 = 5:1) was proved to possess the best catalytic activity. When BiOCl, WO3 and NLCQDs jointly construct the ternary composite catalytic system BiOCl/WO3-2/NLCQDs-Z (Z is the loading amount of NLCQDs, Z = 5, 10, 15 mL), the catalytic activity is significantly improved. Using CO yield as the indicator, BiOCl/WO3-2/NLCQDs-10 was determined to have the best photocatalytic activity. TEM and XPS measurements show that a Z-type heterojunction is formed between BiOCl and WO3, and a built-in electric field is established at the interface. BiOCl/WO3-2/NLCQDs-10 maintained stable catalytic activity for CO2 reduction within 3 h, with a final CO yield of 47.02 μmol · g−1 · h−1, which was 13.3 and 4.2 times higher than BiOCl and BiOCl/WO3-2, respectively. In this study, the separation and transfer path of photo-generated charge were optimized by reasonably constructing BiOCl composite catalytic system, and the photocatalytic performance of CO2 reduction was significantly improved.
