A novel AgO-CoO-CdO/Poly(alanine)-chitosan-reduced graphene oxide (PACSGO) nanocomposite was developed to study the degradation efficiency under visible light irradiation. The AgO, CoO, CdO nanoparticles and AgO-CoO-CdO heterometal oxides were prepared by using the chemical method. The crystallite structure and phase studies were studied by the X-ray diffraction assay. The SEM images were evaluated to explore the morphology of the prepared materials. EDS analysis and FTIR spectra confirmed the formation of nano-materials with high purity. The optical bandgap values were measured via Kubelka-Munk plot showing that the metal oxides produced a new energy state in the electronic level for high photocatalysis efficiency. The incorporation of AgO-CoO-CdO in PACSGO showed a novel nano-photocatalyst for substantial degradation of dye in low process time. The catalysis data displayed that PACSGO based AgO-CoO-CdO nanocomposites ensured a strong potential to degradation of organic dye compounds from water in during photocatalysis reaction. The beneficial anti-pathogenic bacterial performance of the AgO-CoO-CdO/PACSGO nanocomposites was further demonstrated by a substantial reduction in the amount of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and B. cereus medium and increase in inhibition zone value with the addition of the AgO-CoO-CdO/PACSGO nanocomposites.
一种新型的 AgO-CoO-CdO/聚（丙氨酸）-壳聚糖-还原氧化石墨烯（PACSGO）纳米复合材料被开发出来，以研究可见光照射下的降解效率。AgO、CoO、CdO 纳米粒子和 AgO-CoO-CdO 异金属氧化物是通过化学方法制备的。通过 X 射线衍射分析研究了晶相结构和相研究。通过扫描电子显微镜（SEM）图像评估了所制备材料的形态。能谱分析（EDS）和傅里叶变换红外光谱（FTIR）证实了纳米材料的高纯度形成。通过 Kubelka-Munk 图测量了光学带隙值，表明金属氧化物在电子能级上产生了新的能量状态，从而具有高的光催化效率。AgO-CoO-CdO 掺入 PACSGO 中，表现出一种新型的纳米光催化剂，可在短时间内实现染料的大量降解。催化数据表明，基于 PACSGO 的 AgO-CoO-CdO 纳米复合材料在光催化反应中具有很强的降解水中有机染料化合物的潜力。AgO-CoO-CdO/PACSGO 纳米复合材料具有良好的抗病原菌性能，通过添加 AgO-CoO-CdO/PACSGO 纳米复合材料，金黄色葡萄球菌、大肠杆菌、铜绿假单胞菌和蜡状芽孢杆菌培养基的数量显著减少，抑菌圈值增加。
