Abstract An environmentally friendly process for synthesis of rGO/Ag@AgCl Core-shells nanocomposite was developed by Bitter gourd leaf extract. The core-shell morphology was confirmed by STEM-EDX line profile and elemental mapping images. As-synthesized nanocomposite was utilized as photocatalyst for degradation of Clofibric acid (CA) and Naphthol Green B (NGB) from aqueous phase under solar irradiation. As-synthesized nanocomposites showed photodegradation up to 98% of CA and 98.7% of NGB within 40 and 30 min, respectively. Here, we also investigated the optimum amount of nanocomposites for the photodegradation process. ESR analyses confirmed that the active species such as hydroxyl and superoxide anion radicals were mainly accountable for the degradation of organic pollutants. The presence of rGO enhanced the catalytic activity of Ag@AgCl NPs. The as-prepared nanocomposite was also utilized for the removal of biological impurities against bacterial strains. Hence form the present study, it was confirmed that the synthesized rGO-Ag@AgCl nanocomposites act as a potential material for wastewater treatment.

rGO/Ag@AgCl核壳纳米复合材料的简便合成及其作为光催化剂和水净化抗菌剂的多功能功效

摘要 以苦瓜叶提取物为原料，开发了一种环保型rGO/Ag@AgCl核壳纳米复合材料的合成工艺。通过 STEM-EDX 线轮廓和元素映射图像证实了核壳形态。合成的纳米复合材料被用作光催化剂，用于在太阳辐射下从水相中降解氯贝丁酸 (CA) 和萘酚绿 B (NGB)。合成后的纳米复合材料分别在 40 和 30 分钟内光降解高达 98% 的 CA 和 98.7% 的 NGB。在这里，我们还研究了用于光降解过程的纳米复合材料的最佳用量。ESR分析证实羟基和超氧阴离子自由基等活性物质主要负责有机污染物的降解。rGO 的存在增强了 Ag@AgCl NPs 的催化活性。所制备的纳米复合材料还用于去除针对细菌菌株的生物杂质。因此，本研究证实合成的 rGO-Ag@AgCl 纳米复合材料可作为废水处理的潜在材料。
