The Fenton reaction is one of the most effective methods for treating organic wastewater, which is extremely harmful to humans but difficult to treat. However, finding simple, low-cost, and efficient catalysts for the Fenton reaction remains a challenge. In this study, a BSA-Cu(PO) hybrid nanoflower (NF) was synthesized to investigate its peroxidase-like activity for the treatment of organic wastewater. Its morphology, composition, and crystallization had been fully studied and the results confirmed that the NFs were successfully prepared. Subsequently, the origin of the peroxidase-like activity of the NFs was further analyzed, with the results suggesting two reasons: (i) the transformation between Cu(I) and Cu(II) and (ii) nano-effects. Additionally, Congo red was selected as the organic pollutant to simulate the decolorization of wastewater. After 3 h, the decolorization efficiency reached 96%. Furthermore, the NFs exhibited good storage performance, maintaining approximately 90% relative activity after storage for 30 days. In summary, the NFs have great application prospects in the treatment of organic wastewater.
芬顿反应是处理对人类危害极大但难以处理的有机废水的最有效方法之一。然而，寻找简单、低成本、高效的芬顿反应催化剂仍然是一个挑战。本研究合成了一种 BSA-Cu(PO) 杂化纳米花（NF），以研究其过氧化物酶样活性在处理有机废水中的应用。对其形态、组成和结晶进行了充分研究，结果证实 NF 成功制备。随后，进一步分析了 NF 过氧化物酶样活性的起源，结果表明有两个原因：（i）Cu(I)和 Cu(II)之间的转化，（ii）纳米效应。此外，选择刚果红作为有机污染物来模拟废水的脱色。3 小时后，脱色效率达到 96%。此外，NF 表现出良好的储存性能，储存 30 天后，相对活性保持在 90%左右。总之，NF 在处理有机废水方面具有广阔的应用前景。
