Bisphenol A (BPA) has been identified as one of the endocrine disrupting chemicals. However, the issue that BPA widely exists in various environments has puzzled people for decades. To develop highly efficient, easy separation, recyclable and reusable materials for BPA degradation in water, laccase-loaded magnetic nanoflowers (MNFs) were prepared by attaching amino-functionalized magnetic nanoparticles onto the laccase-inorganic hybrid nanoflowers. Characterization results showed that MNFs were spherical, porous and hierarchical structure with an average diameter of 15 μm to which magnetic nanoparticles was successfully attached through electrostatic force. MNFs exhibited excellent catalytic activity on BPA degradation under room temperature in the presence of ABTS. Under optimized conditions, MNFs reached 100% BPA degradation for only 5 min. In addition, it still retained over 92% of its initial activity after 60 days of storage at 4 °C, indicating that its thermal and storage stabilities have been improved. When the MNFs was recycled and reused 5 cycles, only 5% decrease in degradation efficiency of BPA was observed. These results suggest that MNFs possess great efficiency and reusability in the treatment of aqueous solution containing BPA and is a novel promising material.

双酚A（BPA）已被确定为破坏内分泌的化学物质之一。但是，数十年来，BPA广泛存在于各种环境中的问题使人们感到困惑。为了开发用于水中BPA降解的高效，易于分离，可回收和可重复使用的材料，通过将氨基官能化的磁性纳米粒子附着到漆酶-无机杂化纳米花上来制备负载漆酶的磁性纳米花（MNF）。表征结果表明，MNFs为球形，多孔且分层的结构，平均直径为15μm，磁性纳米颗粒通过静电力成功附着在其上。在室温下，存在ABTS的情况下，MNF对BPA降解表现出优异的催化活性。在优化条件下，MNF仅在5分钟内达到100％BPA降解。此外，它在4°C下储存60天后仍保留了其初始活性的92％以上，这表明其热稳定性和储存稳定性得到了改善。当MNFs循环再利用5个循环时，仅观察到BPA降解效率降低了5％。这些结果表明，MNFs在处理含BPA的水溶液中具有很高的效率和可重复使用性，是一种新颖的有前途的材料。
