In this article, we presented a novel WO3-FePc day-night dual reaction centers photocatalyst covalently modified by iron-tetra (N-carbonylacrylic) aminephthalocyanine (FePc), in which WO3 as an electron-storage reservoir and FePc as a photosensitizer and Fenton reaction center, which synergistically improve photocatalytic activity. The photocatalytic performance of WO3-FePc was evaluated using Rhodamine B (RhB) as a model pollutant, and it exhibited remarkable efficiency, with degradation of 93.0% RhB achieved under visible light irradiation for 60 min, and 40.4% RhB degraded in the dark, corresponding to approximately 12.4 times the performance of WO3 and 7.8 times that of FePc. In addition, the removal rates of methylene blue (MB), tetracycline hydrochloride (TC•HCl) and K2Cr2O7 (Cr (VI)) by WO3-FePc under visible light were 99.9%, 99.9% and 81.5% in 20 min, respectively. The rapid charge separation and the synergistic effect between the photocatalytic center and the Fenton center lead to excellent photocatalytic performance. This study prepared a highly efficient photocatalyst WO3-FePc that can act continuously during both day and night, and its distinctive day-night dual reaction center provides a new way to overcome the limitations of traditional photocatalytic technology.

构建新型昼夜双反应中心WO3-FePc光催化剂降解多污染物


在本文中，我们提出了一种由铁-四（N-羰基丙烯酸）胺酞菁（FePc）共价修饰的新型WO3-FePc昼夜双反应中心光催化剂，其中WO3作为电子存储库，FePc作为光敏剂和Fenton反应中心，协同提高光催化活性。使用罗丹明B（RhB）作为模型污染物评估WO3-FePc的光催化性能，其表现出显着的效率，在可见光照射60分钟下降解了93.0%的RhB，在黑暗中降解了40.4%的RhB。相当于WO3性能的约12.4倍和FePc性能的7.8倍。此外，WO3-FePc在可见光下20 min对亚甲基蓝（MB）、盐酸四环素（TC•HCl）和K2Cr2O7（Cr（VI））的去除率分别为99.9%、99.9%和81.5%。快速的电荷分离以及光催化中心与芬顿中心之间的协同效应导致了优异的光催化性能。该研究制备了一种可以在白天和夜间连续作用的高效光催化剂WO3-FePc，其独特的昼夜双反应中心为克服传统光催化技术的局限性提供了新的途径。
