The advancement of technology has resulted in severe issues in the natural environment, notably organic water contamination that poses a significant threat to living organisms. To mitigate such problems, various technological solutions have been developed to treat water pollution. The emergence of photocatalytic semiconductor technology has enabled the utilization of numerous novel semiconductor composites for pollution control due to their high efficacy and eco-friendliness. In this paper, TpTt/CdS composites were produced via a simple two-step process, and the resulting samples were characterized using X-ray diffraction, field emission scanning electron microscopy, Fourier transform infrared, X-ray photoelectron spectroscopy, ultraviolet (UV)–visible and photodegradation experiments using methylene blue to simulate organic pollutants. The experimental findings reveal that the composite structure system enhances the radiation absorption capacity of CdS in the UV range, as well as the adsorption capability of organic pollutants. This introduces a fresh concept for modifying semiconductor composite structures and highlights the considerable potential of CdS in degrading organic contaminants.

技术的进步导致自然环境出现严重问题，特别是有机水污染，对生物体构成重大威胁。为了缓解这些问题，已经开发了各种技术解决方案来处理水污染。光催化半导体技术的出现，由于其高效和环保，使得许多新型半导体复合材料能够用于污染控制。本文通过简单的两步工艺生产了 TpTt/CdS 复合材料，并使用 X 射线衍射、场发射扫描电子显微镜、傅里叶变换红外、X 射线光电子能谱、紫外 (UV) 等手段对所得样品进行了表征。 –使用亚甲蓝模拟有机污染物的可见光和光降解实验。实验结果表明，复合结构体系增强了CdS在紫外范围内的辐射吸收能力，以及对有机污染物的吸附能力。这引入了修改半导体复合结构的新概念，并凸显了 CdS 在降解有机污染物方面的巨大潜力。
