Abstract Photocatalytic splitting water is a new clean green technology that has become a research hotspot in the scientific community. Among them, cadmium sulfide (CdS) is a classic photocatalyst. But applications are limited due to photo-corrosion and fast electron-hole recombination. Herein, hollow CdS tubes with special morphology were successfully modified by simple vapor deposition of graphitic carbon nitride (CN). The obtained 1D binary heterojunction photocatalyst showed good photohydrolysis hydrogen production performance under visible light (λ ≥ 400 nm). The introduction of CN prevented photo-corrosion of CdS, so it also had great cycle performance. At the same time, the proper amount of CN deposition was studied. The most suitable sample (CN0.5-CdS) showed the best hydrogen release rate (392.84 μmol g−1 h−1) within 4 h. Finally, based on a series of analysis datas of photocatalysts, its special tubular structure and possible catalytic mechanism were further discussed.

g-C3N4/CdS可控合成异质结空心纳米管：增强可见光催化制氢性能

摘要 光催化分解水是一种新型清洁绿色技术，已成为科学界的研究热点。其中，硫化镉（CdS）是一种经典的光催化剂。但由于光腐蚀和快速电子-空穴复合，应用受到限制。在此，通过石墨氮化碳 (CN) 的简单气相沉积成功地改性了具有特殊形态的空心 CdS 管。所得一维二元异质结光催化剂在可见光（λ≥400 nm）下表现出良好的光水解产氢性能。CN的引入防止了CdS的光腐蚀，因此它也具有很好的循环性能。同时研究了适量的CN沉积。最合适的样品（CN0.5-CdS）在 4 小时内显示出最佳的氢释放速率（392.84 μmol g-1 h-1）。最后，
