In our present study, we have reported the fabrication of a simple, low-cost and ultra-violet active Nickel oxide Substituted . peel extract photocatalyst. The synthesized photocatalyst samples were characterized by a combination of various physicochemical techniques. The degradation of Rhodamin b (RhB) shows excellent durability and recyclability properties. The remarkable enhancement in photoactivity under ultra-violet light irradiation can be attributed to the decrease in band gap by plant extract substitution. In our investigation, we report for the first time the synthesized NiO NPs using Rambutan (.) undergo photocatalytic activity studies against cationic dye, Rhodamin b under UV light illumination. The result shows that the NiO NPs shows high degradation activity against RhB (92.3%). A plausible mechanism for the formation of NiO NPs from the biological source was also proposed. The outcome of the present study is an effective approach to design environmental friendly material for treating dying industry effluent.
在我们目前的研究中，我们报道了一种简单、低成本且具有紫外活性的氧化镍替代果皮提取物光催化剂的制备。通过多种物理化学技术对合成的光催化剂样品进行了表征。罗丹明B（RhB）的降解显示出优异的耐久性和可回收性。紫外光照射下光活性的显著增强可归因于植物提取物替代导致的带隙减小。在我们的研究中，我们首次报道了使用红毛丹合成的氧化镍纳米颗粒在紫外光照射下对阳离子染料罗丹明B进行光催化活性研究。结果表明，氧化镍纳米颗粒对RhB具有高降解活性（92.3%）。还提出了一种从生物源形成氧化镍纳米颗粒的合理机制。本研究的结果是一种设计用于处理印染工业废水的环保材料的有效方法。
