Investigation of\nMorphology-Modified Bi<sub>2</sub>WO<sub>6</sub> Nanoparticles with\nSurface Plasmon Resonance Effect\nfor the Enhanced Photocatalytic Degradation of Organic Dyes: Toxicity\nEstimation and In Silico Studies

The advanced oxidation process involves photocatalytic\ndegradation,\nwhich is a propitious method of treating wastewater. However, to augment\nthe photocatalytic activity of photocatalysts, the surface plasmon\nresonance (SPR) method is a highly promising candidate. Herein, we\nprepared bismuth (Bi) and tungsten (W)-based metal oxide (Bi<sub>2</sub>WO<sub>6</sub>) coupled with Ag as a semiconducting metal oxide-based\nplasmon resonance photocatalyst. Despite the SPR effect, the aggregation\nof particles lowers the efficiency of degradation. To get the better\nof it, morphology tuning agents and visible light-absorbing agents\nlike CTAB (cetyltrimethylammonium bromide) were used. The prepared\ncomposite materials were characterized using sophisticated analytical\ninstruments. The prepared materials were tested for their catalytic\nactivity against Victoria Blue (VB) and Auramine O (AO) dyes. The\ncomposite material showed superior catalytic activity over the individual\nmaterial, 97% and 98% for VB and AO, respectively. In addition, the\ntoxicity of the byproducts (mutagenic toxicity, lethal concentration\n50 (LC-50), and lethal dose (LD-50)) was estimated, and the detailed\nDFT interpretations were studied. Finally, a real-time agricultural\napplication using post-treated water was conducted at the Epipremnum aureum plant.
