With the worldwide industrial growth, major concern is rapid surge in water pollution. Notably, the water is contaminated by strong industrial dyes and pathogenic microorganisms. To address the issue, a simple heterostructure GO/Ag₂O was synthesized in room temperature, which can serve the purpose of industrial waste management. In general, Ag₂O nanostructures with absorptivity in NIR range is able to absorb 57% of solar spectrum, but our synthesized Ag₂O nanowires can absorb Visible-NIR spectral range (peak ~ 850 nm) due to presence of multiple energy states, confirmed by the density of states (DOS) of Ag₂O using density functional theory (DFT) analysis. Developing a nanocomposite with graphene oxide exhibited blue shifting of absorption maximum at 700 nm and improved absorptivity covering the entire solar spectrum (200–1800 nm). The DFT analysis of designed geometrical relaxed structure of GO/Ag₂O approved the unique optical properties of nanocomposite. The nanocomposite degraded a very strong medical dye (Safranin-O) for 40 min white light exposures. In addition, our nanocomposite also showed antibacterial activity against E. coli with an MBC ~ 0.01 mg/ml. Molecular Docking analysis also established the improved interaction of an E.coli ribosomal and membrane protein with GO in nanocomposite in comparison with that of pure GO, which supports the experimental results. Fast charge transfer between Ag₂O and GO increases the super oxide and hydroxide radicals in our synthesized hetero-system, which results excellent solar photocatalytic activity and ROS species to destroy the bacterial colonies.

随着世界范围内工业的增长，主要关注的是水污染的迅速增加。值得注意的是，水被强工业染料和病原微生物污染。为了解决这个问题，在室温下合成了一种简单的异质结构GO/Ag _{2 O，可以用于工业废物管理。}一般来说，在近红外范围内具有吸收率的 Ag ₂ O 纳米结构能够吸收 57% 的太阳光谱，但我们合成的 Ag ₂ O 纳米线由于存在多种能态，可以吸收可见近红外光谱范围（峰值 ~ 850 nm），由 Ag ₂的态密度 (DOS) 证实O 使用密度泛函理论 (DFT) 分析。用氧化石墨烯开发纳米复合材料在 700 nm 处显示出最大吸收蓝移，并提高了覆盖整个太阳光谱（200-1800 nm）的吸收率。_{GO/Ag 2} O设计的几何松弛结构的DFT分析证实了纳米复合材料的独特光学性质。纳米复合材料在 40 分钟的白光照射下降解了一种非常强的医用染料（番红-O）。此外，我们的纳米复合材料还显示出对大肠杆菌的抗菌活性，MBC ~ 0.01 mg/ml。分子对接分析还确定了大肠杆菌的改进相互作用核糖体和膜蛋白与 GO 在纳米复合材料中与纯 GO 的比较，这支持了实验结果。Ag ₂ O 和 GO 之间的快速电荷转移增加了我们合成的异质体系中的超氧化物和氢氧化物自由基，从而产生出色的太阳能光催化活性和 ROS 物种以破坏细菌菌落。
