AI Article Synopsis
- Researchers developed Ag-doped bismuth oxybromide (Ag-BiOBr) nanoplates to enhance photocatalytic efficiency under visible light by using a one-step hydrothermal method.
- The modification resulted in a shift of the absorption edge from 453 nm to 510 nm, significantly improving the material's ability to absorb visible light compared to standard BiOBr.
- Ag-BiOBr demonstrated a degradation efficiency for Bisphenol A (BPA) that was approximately double that of BiOBr, highlighting its potential for addressing organic pollution in water treatment applications.
Article Abstract
Based on the low utilization rate of visible light and the high-charge carriers-recombination efficiency of bismuth oxybromide (BiOBr), in this work, noble metal Ag was used to modify BiOBr, and Ag-doped BiOBr nanoplates (Ag-BiOBr) were obtained through a one-step hydrothermal method. Compared with BiOBr, the absorption edge of Ag-BiOBr showed a redshift from 453 nm to 510 nm, and the absorption efficiency of visible light was, obviously, improved. Bisphenol A (BPA) was chosen as the target pollutant, to evaluate the photocatalytic performance of the samples. Ag-BiOBr showed the highest degradation efficiency. The intrinsic photocatalytic activity of Ag-BiOBr, under visible light, was approximately twice as high as that of BiOBr. In this way, a new visible-light-driven photocatalyst was proposed, to fight against organic pollution, which provides a promising strategy for water and wastewater treatment.
