The synergistic effect of bimetallic co-incorporated metal oxides have gained enormous attention due to their unique optoelectronic properties. Herein, we present the green synthesis of ZnO, Cu-incorporated ZnO, Mn-incorporated ZnO, and Cu-Mn co-incorporated nanoparticles (ZnO NPs, CuZnO NPs, MnZnO NPs, MnCuZnO NPs) for antimicrobial and photocatalytic reduction applications using corn silk extract and industrial metal wastes. The as-synthesized NPs were characterized by using UV-visible absorption spectroscopy (UV-Vis), photoluminescence (PL) spectroscopy, Fourier-transformed infrared spectroscopy (FT-IR), powdered x-ray diffraction (XRD), and scanning electron microscopy (SEM). CuZnO, MnZnO, and MnCuZnO NPs efficiently inhibited bacterial culture growth. The photocatalytic reduction activity of as-synthesized NPs against the different concentrations of 4-nitrophenol (4-NP) in water was also investigated. CuZnO and MnCuZnO nanoparticles were to be efficient photocatalysts for reducing 4-NP into 4-aminophenol (4-AP). RESEARCH HIGHLIGHTS: Green synthesis of nanomaterials by agricultural and industrial wastes Cu and Mn co-incorporated ZnO NPs have shown good photocatalysis and antimicrobial activities Green approach for waste conversion to value-added products.
双金属共掺杂金属氧化物由于其独特的光电性能而引起了极大的关注。在此，我们使用玉米丝提取物和工业金属废料，通过绿色合成法制备了 ZnO、Cu 掺杂 ZnO、Mn 掺杂 ZnO 和 Cu-Mn 共掺杂纳米粒子（ZnO NPs、CuZnO NPs、MnZnO NPs、MnCuZnO NPs），并将其用于抗菌和光催化还原应用。所合成的 NPs 通过使用紫外-可见吸收光谱 (UV-Vis)、光致发光 (PL) 光谱、傅里叶变换红外光谱 (FT-IR)、粉末 X 射线衍射 (XRD) 和扫描电子显微镜 (SEM) 进行了表征。CuZnO、MnZnO 和 MnCuZnO NPs 有效地抑制了细菌培养物的生长。还研究了合成的 NPs 对水中不同浓度的 4-硝基苯酚 (4-NP) 的光催化还原活性。CuZnO 和 MnCuZnO 纳米粒子是将 4-NP 还原为 4-氨基酚 (4-AP) 的有效光催化剂。研究亮点：利用农业和工业废物进行纳米材料的绿色合成 Cu 和 Mn 共掺杂 ZnO NPs 表现出良好的光催化和抗菌活性 将废物转化为增值产品的绿色方法。
