摘要

以SiO₂微球为硬模板,3-氨基-5-巯基-1,2,4-三氮唑为前驱体,经高温炭化后除去硬模板得到硫掺杂的氮化碳材料。通过扫描电镜(SEM)、物理吸附仪(BET)、X射线衍射仪(XRD)、X射线光电子能谱仪(XPS)和紫外-可见光谱仪(UV-Vis)等研究手段对制备的材料进行表征分析。将硫掺杂氮化碳材料应用于可见光催化降解有机污染物罗丹明B,通过改变不同条件研究其光催化活性。结果表明:掺杂后的禁带宽度减小是光催化性能提高的主要原因。

Abstract

The sulfur-doped carbon nitride(S-C₂N₂) materials were prepared by high-temperature carbonization and the hard template was removed,which 3-amino-5-mercapto-1,2,4-triazole was used as a precursor.Scanning electron microscopy (SEM),physical adsorption (BET),X-ray diffraction (XRD),X-ray photoelectron spectroscopy (XPS) and UV-Vis were used to characterize the prepared materials.The prepared material was applied to study the visible light catalytic activity degradation of organic pollutants rhodamine B under different experimental conditions.The results demonstrated that the reduction of band gap after doping was the main reason for the improvement of photocatalytic performance.
