Abstract

This study investigates the synthesis, characterization, and photocatalytic performance of Copper Oxide/Nickel Oxide (CuO/NiO) hybrid composites, produced via a hydrothermal method. X-ray diffraction (XRD) confirmed the successful formation of CuO/NiO hybrids, highlighting distinct peaks indicative of both CuO and NiO phases. Scanning electron microscopy (SEM) displayed well-defined, uniformly distributed particles, while energy-dispersive X-ray spectroscopy (EDX) validated the stoichiometric composition of the hybrids. The photocatalytic efficacy of the CuO/NiO composites was evaluated under sunlight, demonstrating significantly enhanced degradation of methylene blue (MB) dye compared to pure CuO. This improvement is attributed to the synergistic interaction between CuO and NiO, which facilitates efficient organic pollutant breakdown. Our findings suggest that CuO/NiO hybrids are promising candidates for advanced water treatment technologies, offering a sustainable and efficient approach to mitigating organic pollutants using sunlight-driven photocatalysis.

水热合成CuO/NiO复合材料作为一种很有前途的光催化剂用于日光驱动的有机污染物降解
本文研究了水热法制备的氧化铜/氧化镍(CuO/NiO)杂化复合材料的合成、表征及其光催化性能。x射线衍射(XRD)证实了CuO/NiO杂化物的成功形成,突出了CuO和NiO相的明显峰。扫描电子显微镜(SEM)显示了明确的、均匀分布的颗粒,而能量色散x射线光谱(EDX)证实了杂化物的化学计量组成。在日光下评价了CuO/NiO复合材料的光催化效果,结果表明,与纯CuO相比,CuO/NiO复合材料对亚甲基蓝(MB)染料的降解效果显著提高。这种改善是由于CuO和NiO之间的协同作用,促进了有机污染物的有效分解。我们的研究结果表明,CuO/NiO混合物是先进水处理技术的有希望的候选者,为利用阳光驱动的光催化减少有机污染物提供了一种可持续和有效的方法。
