摘要

采用原位合成法制备了α-nBACoPc/SnO2 复合材料，并通过傅立叶变换红外光谱（FT-IR）、X 射线粉末衍射（XRD）和 X 射线光电子能谱（XPS）对其进行了表征。以罗丹明 B 为模拟污染物进行光催化降解实验。复合材料的光催化降解率为 83.3%，高于单独使用 α-nBACoPc 和 SnO2 的光催化降解率。复合材料中的 Co-O 键增强了电子从酞菁向二氧化锡传导带的转移，提高了光的利用率，加强了酞菁钴和二氧化锡的协同作用。此外，复合材料还具有良好的稳定性和可回收性。

A New Type of Composite Catalyst α-nBACoPc/SnO2 Synergistic Photo-Catalytic Degradation of Dyes

The α-nBACoPc/SnO₂ composites were prepared using the in situ synthesis method and characterized by Fourier transform infrared (FT-IR), X-ray powder diff raction (XRD), X-ray photoelectron spectroscopy (XPS), and confirmed by the loading of amino cobalt phthalocyanine on SnO₂. Conduct photocatalytic degradation experiments used rhodamine B as a simulated pollutant. The composite exhibited a photo-catalytic degradation rate of 83.3%, which was higher than that of α-nBACoPc and SnO₂ alone. The Co–O bond in the composite material enhances the transfer of electrons from phthalocyanine to the SnO₂ conduction band, improving light utilization and strengthening the synergistic impact of cobalt phthalocyanine and SnO₂. Furthermore, the composites demonstrated good stability and recyclability.
