The present scenario of water insecurity (poor availability and accessibility to clean healthy when needed) denotes the preponderance environmental damage caused by effluents or waste runoff from industries, such as dye textile industries. polluted waters have led terrible sonorous negative impacts on ecosystem econetworking, thus, urging for a sustainably suitable substitute tackle annul noxious constraint posse hazardous effluent. Several chemical physical methods treating effluent are now in use, but they time‐consuming, expensive, inefficient. Interestingly, nanoparticles egressed superior answer efficient removal degradation, because their reactivity exceptional surface characteristics. As result, use metal nanomaterials treatment runoffs has been thoroughly investigated. study used major scientific databases SciFinder, Scopus, PubMed, Google Scholar, Science Direct conduct comprehensive review publicly available literature. Degradation, effluent, green nanoparticles, pollution were keywords find scholarly papers. Efforts made figure out explain mechanism how long degradation will take effective plant biosynthesized is. In addition, role bimetallic also investigated with remarkable feat current level knowledge about biogenic common is summarized this paper.

Abstract Nanotechnology is rapidly becoming more and important in today's technological world as the need for industry increases with human well-being. In this study, we synthesized SnO 2 nanoparticles (NPs) using an environmentally friendly method or green from Croton macrostachyus leaf extract, leading to transformation of UV absorbance visible by reducing band gap energy. The products underwent UV, FTIR, XRD, SEM, EDX, XPS, BET, DLS characterization. Characterization via UV–Vis spectroscopy confirmed shift towards spectrum, indicating potential enhanced photocatalytic activity under light irradiation. energy as-synthesized was 3.03 eV, 2.71 2.61 2.41 eV 1:1, 1:2, 1:3, 1:4 sample ratios, respectively. average crystal size 32.18 nm very fine flakes tiny agglomerate structures obtained. green-synthesized explored irradiation degradation rhodamine B (RhB) methylene blue (MB), which were widespread fabric pollutants. It finally that prepared NPs actively used degradation.
