摘要

本研究利用四氰乙烯(TCNE)与g-C3N4共聚,通过溶剂热合成法制备了PTCN/SnS2异质结复合材料。表征表明,二次煅烧引入的质子化氮化碳(PCN)修饰了g-C3N4的结构(TEM),同时保留了其类似石墨烯的层内/层间框架(XRD/FTIR)。光致发光分析表明,tcne -共聚材料的载流子重组受到抑制,表现为发射强度降低,载流子寿命延长,从而提高了光催化活性。优化后的复合材料在可见光下对四环素和土霉素的降解率分别为81.10%和90.43%,其中PTCN/SnS2-10对金四环素的降解率为64.01%。增强的载流子迁移和分离机制使其性能优于纯相SnS2和g-C3N4。本研究通过形态学和电子调制展示了一种合理的界面工程策略,为设计高效的异质结光催化剂来对抗有机污染物提供了一种可推广的方法。

Synthesis of Tetracyanoethylene Co-Graphite Phase Carbon Nitride PTCN/SnS2 and Degradation Analysis of Oxytetracycline
This study fabricated PTCN/SnS2 heterojunction composites via solvothermal synthesis, utilizing tetracyanoethylene (TCNE) copolymerization with g-C3N4 for morphology control. Characterization revealed that secondary calcination-introduced protonated carbon nitride (PCN) modified g-C3N4’s structure (TEM) while retaining its graphene-like intra/interlayer framework (XRD/FTIR). Photoluminescence analysis indicated suppressed carrier recombination in TCNE-copolymerized materials, evidenced by reduced emission intensity and prolonged carrier lifetime, thereby enhancing the photocatalytic activity. The optimized composites achieved 81.10% tetracycline and 90.43% oxytetracycline degradation under visible light, with PTCN/SnS2-10 exhibiting 64.01% efficiency for chlortetracycline. Enhanced carrier migration and separation mechanisms enabled superior performance over that of pure-phase SnS2 and g-C3N4. This work demonstrates a rational interface engineering strategy through morphological and electronic modulation, offering a generalizable approach for designing efficient heterojunction photocatalysts to combat organic pollutants.
