The Effect of Ag Decoration on the Photocatalytic Performance of Doped-Bi2wo6For Environmental Applications

Pollutants in the water cause environmental issues and have a negative impact on human health. therefore, a variety of wastewater treatment strategies have been investigated in order to address growing environmental concerns and alleviate the detrimental effects of water contaminants. photocatalysis is a low-cost, efficient, and environmentally friendly approach for degrading pollutants. in the last decade, bi2wo6 (bwo) nanostructures, because of their non-toxicity, their great physical and chemical properties, their suitable band gap and their good photocatalytic efficiency under visible light, were regarded as a viable choice for photocatalytic degradation of waste water. the quick recombination of photogenerated pairs of electron holes however adversely impacts the overall performance of bi2wo6 for pollutant degradation. band gap engineering via doping and surface decorating of bi2wo6 semiconductors with plasmonic nanoparticles significantly boosts their photocatalytic effectiveness, according to ongoing work. in this study, ag nanoparticles were successfully decorated on the surface of the bwo-mo photocatalyst and its properties were characterized. ag nanoparticles may act as electron traps, reducing electron-hole pair recombination. furthermore, using ag nanoparticles can cause scattering and then absorption of more visible light. as a result, the ag-decorated bi2wo6-mo photocatalyst revealed a significant enhancement (62%) in the photocatalytic degradation efficiency compared to the unmodified pure bi2wo6 (19%) due to the synergic contribution of the decrease in band gap by mo doping and ag-induced surface plasmon resonance (spr) effects.
