In this work, AgI photocatalysts with significantly enhanced sunlight-driven photocatalytic performance were prepared with the assistance of polyethylene glycol (PEG) via a facile precipitation method. Brunauer-Emmett-Teller (BET), X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), UV–Vis diffuse reflectance spectra (DRS), surface photovoltage spectroscopy (SPS) were used to study the samples. The level of ·O₂⁻ was studied using nitroblue tetrazolium (NBT) -·O₂⁻ exclusive reaction. The result exhibits that ·O₂⁻ is the primary active free radicals. Photocatalytic performance of the photocatalysts for destruction of rhodamine B (RhB) and tetracycline (TC) was evaluated using a 500W Xe lamp as the light source (simulated sunlight). The photocatalytic activity of PEG-AgI is more than 3 times of that of AgI.

在这项工作中，借助聚乙二醇（PEG）通过一种简便的沉淀方法制备了具有明显增强的日光驱动的光催化性能的AgI光催化剂。Brunauer-Emmett-Teller（BET），X射线衍射图（XRD），扫描电子显微镜（SEM），X射线光电子能谱（XPS），UV-Vis漫反射光谱（DRS），表面光电压能谱（SPS）被用来研究样本。的水平·O2 ₂ ^-用氮蓝四唑（NBT）进行了研究- ·O2 ₂ ^-独家反应。结果展品，·O2 ₂ ^-是主要的活性自由基。使用500W Xe灯作为光源（模拟太阳光）评估了光催化剂对若丹明B（RhB）和四环素（TC）的破坏的光催化性能。PEG-AgI的光催化活性是AgI的3倍以上。
