One important topic to recovery the photocatalytic process is to prevent the recombination of electrons and holes generated by light excitation of the photocatalyst. Different strategies have been used for this purpose. Composite of compounds is an appropriate way to reduce the recombination. On the other hand, to optimize the use of visible light, components can be composited with visible active components. In this article, sensitization with porphyrin and tin porphyrin complex was carried out using solar light for more activation of composite in visible light. The results on the synthesis of BiOBr/BiOCl/PANI@TCPP (BPT) and BiOBr/BiOCl/PANI@SnTCPP (BPST) nanocomposites were reported using a simple method. The resulting nanocomposites were characterized by the XRD, FT-IR, FE-SEM equipped with EDS, PL, Raman, and UV–Vis DRS analytical techniques. Furthermore, the photocatalytic activity of nanocomposites sensitized with porphyrin for degradation of methyl orange (MO) as the model organic pollutant was investigated. The maximum degradation efficiency of 96% is achieved under visible light irradiation within 10 min. The photocatalytic performance of BPT and BPST nanocomposites was much higher than that of BiOBr/BiOCl/PANI (BP).

恢复光催化过程的一个重要主题是防止由于光催化剂的光激发而产生的电子和空穴的复合。为此已使用了不同的策略。化合物的复合是减少重组的合适方法。另一方面，为了优化可见光的使用，可以将组件与可见的活性组件复合。在本文中，使用太阳光对卟啉和锡卟啉配合物进行敏化，以在可见光中进一步激活复合物。使用简单的方法报道了BiOBr / BiOCl / PANI @ TCPP（BPT）和BiOBr / BiOCl / PANI @ SnTCPP（BPST）纳米复合材料的合成结果。所得的纳米复合材料通过XRD，FT-IR，FE-SEM进行了表征，配备了EDS，PL，拉曼和UV-Vis DRS分析技术。此外，研究了用卟啉敏化的纳米复合材料的光催化活性，以降解作为模型有机污染物的甲基橙（MO）。在10分钟内的可见光照射下，最大降解效率达到96％。BPT和BPST纳米复合材料的光催化性能远高于BiOBr / BiOCl / PANI（BP）。
