Abstract

This research highlights the significant role of green synthesis in the production of copper oxide (CuO) nanoparticles by using natural extracts as reducing agents. These nanoparticles have shown promising potential in two key applications: photocatalytic degradation of industrial dye effluents and electrochemical sensing of ciprofloxacin. The study found that Arundinaria gigantea leaf extract is an effective reducing agent for synthesizing well-defined crystalline structure CuO nanoparticles, with an average size of 36 nm. The CuO nanoparticles have demonstrated high efficiency in photocatalytic applications, effectively degrading AR88 dye under UV irradiation, making them a viable solution for eco-friendly water purification. Additionally, when incorporated into an electrochemical sensor, these CuO nanoparticles have improved sensitivity and selectivity in detecting ciprofloxacin in aqueous solutions with high accuracy and precision. This study emphasizes the versatility and effectiveness of green-synthesized CuO nanoparticles for various practical uses.

CuO纳米颗粒的绿色合成：一种很有前途的光催化和电化学传感器材料

这项研究强调了绿色合成在使用天然提取物作为还原剂生产氧化铜（CuO）纳米颗粒中的重要作用。这些纳米颗粒在两个关键应用中显示出了很好的潜力：光催化降解工业染料废水和电化学传感环丙沙星。该研究发现，大毒蜥叶提取物是一种有效的还原剂，可以合成平均尺寸为36纳米的晶体结构明确的CuO纳米颗粒。CuO纳米颗粒在光催化应用中表现出高效性，在紫外线照射下有效降解AR88染料，使其成为环保净水的可行解决方案。此外，当结合到电化学传感器中时，这些CuO纳米颗粒在高精度和精密度检测水溶液中的环丙沙星方面提高了灵敏度和选择性。本研究强调了绿色合成的CuO纳米颗粒在各种实际应用中的通用性和有效性。
