Abstract In this manuscript, the synthesis of ternary nanocomposites NiO-CuO-RGO (NCR) via hydrothermal route by the different GO loading amounts resulting in preparation of NCR-5% and NCR-10% composites were discussed. The prepared composites were excessively studied by X-ray diffraction, Fourier transform infrared spectroscopy, Raman, Field emission scanning electron microscopy, energy dispersive X-ray, transmission electron microscopy, Photoluminescence and UV–Visible spectrophotometer to execute their electronic, optical and spectroscopic properties. However, the XRD and EDX results confirmed the pure phase formation of NCR composites without impurities. Later, the photocatalytic efficiency of prepared samples was examined over model organic pollutant Brilliant green (BG) degradation under UV–Visible light irradiations. Interestingly, the tested composites possess better photocatalytic efficiency than previous reports, predominantly, NCR-10% was most effective for the degradation percentage rate of BG dye (91%) in 60 min under visible light irradiation. This catalyst shown greater stability and was recycled for five successive runs. Unambiguously as we expected, NCR-5% composite was effectively degraded BG dye (80%) under UV light than NCR-10%composite which revealed less degradation rate. In addition, the indolence of pathogens also examined against two different pathogens and these results clearly stated that NCR-10% composite was acted as benign antimicrobial agent.

基于还原氧化石墨烯的 NiO 和 CuO 三元纳米复合材料增强紫外-可见光触发光催化降解亮绿及其抗菌活性

摘要 在本手稿中，讨论了通过水热法通过不同 GO 负载量制备 NCR-5% 和 NCR-10% 复合材料的三元纳米复合材料 NiO-CuO-RGO (NCR)。通过 X 射线衍射、傅里叶变换红外光谱、拉曼、场发射扫描电子显微镜、能量色散 X 射线、透射电子显微镜、光致发光和紫外-可见分光光度计对制备的复合材料进行了过度研究，以执行其电子、光学和光谱性能. 然而，XRD 和 EDX 结果证实了 NCR 复合材料的纯相形成，没有杂质。后来，在紫外-可见光照射下，通过模型有机污染物亮绿 (BG) 降解来检查制备样品的光催化效率。有趣的是，测试的复合材料具有比之前报道更好的光催化效率，主要是 NCR-10% 在可见光照射下 60 分钟内对 BG 染料的降解百分比（91%）最有效。这种催化剂表现出更高的稳定性，并被循环使用五次连续运行。正如我们所料，NCR-5% 复合材料在紫外光下比 NCR-10% 复合材料能有效降解 BG 染料 (80%)，后者显示出更低的降解率。此外，还针对两种不同的病原体检测了病原体的惰性，这些结果清楚地表明 NCR-10% 复合物可作为良性抗菌剂。这种催化剂表现出更高的稳定性，并被循环使用五次连续运行。正如我们所料，NCR-5% 复合材料在紫外光下比 NCR-10% 复合材料能有效降解 BG 染料 (80%)，后者显示出更低的降解率。此外，还针对两种不同的病原体检测了病原体的惰性，这些结果清楚地表明 NCR-10% 复合物可作为良性抗菌剂。这种催化剂表现出更高的稳定性，并被循环使用五次连续运行。正如我们所料，NCR-5% 复合材料在紫外光下比 NCR-10% 复合材料能有效降解 BG 染料 (80%)，后者显示出更低的降解率。此外，还针对两种不同的病原体检测了病原体的惰性，这些结果清楚地表明 NCR-10% 复合物可作为良性抗菌剂。
