The development of simple and economical preparation of magnetic core-shell heterostructures remains a formidable challenge. This work proposed a novel facile fabrication approach for bifunctional Fe₃O₄@TiO₂ core-shell photocatalyst through an in-situ synthesis technique at room temperature. The important performances of as-synthesized photocatalyst were characterized and the synthetic conditions were optimized. The results proved that it exhibited good photocatalytic ability under UV light irradiation since 97.56% of methylene blue (MB) was degraded after 90 min irradiation and kept good degradation efficiency and recovery after 5 cycles, indicating the great potential in practical applications.

磁性核-壳异质结构的简单而经济的制备方法的发展仍然是一个巨大的挑战。这项工作提出了一种新颖的简便方法，通过在室温下原位合成技术制备双功能Fe ₃ O ₄ @TiO ₂核壳型光催化剂。表征了合成后光催化剂的重要性能，优化了合成条件。结果证明，在90分钟的照射后降解了97.56％的亚甲基蓝（MB），并在5个循环后仍保持良好的降解效率和回收率，因此在紫外光照射下具有良好的光催化能力，表明在实际应用中具有很大的潜力。
