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.
