A new broad-spectrum responsive organic-inorganic hybrid photocatalyst (PI@BWO) was successfully prepared by in-situ growing Bi₂WO₆ nanosheets onto the surface of π-π stacking perylene imide. The obtained PI@BWO hybrids with different composition exhibited enhanced photocatalytic activity for Bisphenol A (BPA) degradation. Among them, 30% PI@BWO exhibited optimal photocatalytic degradation efficiency, which is 2.6 and 3.9 times higher than that of pristine PI and BWO, respectively. Furthermore, PI@BWO also performed good stability and recyclability. Remarkably, the π-conjugation of PI facilitated the separation of charge carriers and improved the utilization of sunlight for PI@BWO. The introduction of BWO nanosheets also enhanced the adsorption capacity for contaminants and provided much more plentiful active sites, promoting the next photocatalytic reaction. Most importantly, PI@BWO could produce abundant reactive species (such as ¹O₂ and ·OH) via the charge carrier transfer and energy transfer dual transfer approach, therefore leading to stronger oxidation ability. The photocatalytic degradation mechanism and pathway of the PI@BWO hybrids were finally proposed. Overall, this present work might provide a new insight into the designing and preparation of efficient organic-inorganic hybrid photocatalysts for environmental-friendly removal of hazardous organic pollutants.

通过原位生长Bi ₂ WO ₆成功制备了一种新型的广谱响应性有机-无机杂化光催化剂（PI @ BWO）。π-π堆叠per酰亚胺表面形成纳米片。获得的具有不同组成的PI @ BWO杂种对双酚A（BPA）降解表现出增强的光催化活性。其中30％的PI @ BWO表现出最佳的光催化降解效率，分别是原始PI和BWO的2.6和3.9倍。此外，PI @ BWO还具有良好的稳定性和可回收性。值得注意的是，PI的π共轭促进了电荷载流子的分离，并提高了PI @ BWO的太阳光利用率。BWO纳米片的引入还增强了对污染物的吸附能力，并提供了更多的活性位，从而促进了下一步的光催化反应。最重要的是，PI @ BWO可以产生丰富的反应物种（例如¹ O₂和？OH）通过电荷载流子转移和能量转移的双重转移方法，因此导致较强的氧化能力。最终提出了PI @ BWO杂种的光催化降解机理和途径。总体而言，这项工作可能会为设计和制备有效的有机-无机杂化光催化剂提供新的见解，以用于环境友好地去除有害有机污染物。
