AI Technical Summary
Existing semiconductor photocatalysts have difficulty effectively utilizing near-infrared light in the solar spectrum, which limits their application in treating microplastics in aquatic environments.
By introducing anion and cation defects into bismuth sulfide photocatalysts and treating them with sodium borohydride and sodium hydroxide, a dual-defect regulated bismuth sulfide photocatalyst was constructed, which broadened its near-infrared spectral absorption range and improved its photon absorption rate and the separation ability of photogenerated electron-hole pairs.
It achieves highly efficient degradation of antibiotics under near-infrared light, improves photocatalytic performance, broadens the spectral utilization range, and has a green and environmentally friendly preparation process.
