| 摘要: 采用化学还原法将非贵金属钴纳米颗粒沉积到氮化碳纳米管（C3N4 NTs）内外管壁，制备了Co/C3N4 NTs复合光催化剂。使用多种分析表征手段对Co/C3N4 NTs的形貌和结构进行分析，并比较Co负载量对复合材料可见光光催化产氢性能的影响。结果表明，该金属-半导体异质结可有效增强光生电子-空穴的分离速率。经可见光照射2 h后，当Co负载量为质量分数5%时具有最佳产氢量，且产氢速率为纯C3N4 NTs的1.7倍。 | |

| Abstract: The low-cost cobalt nanoparticles were deposited on the channels of carbon nitride nanotubes (C3N4 NTs) by a chemical reduction process. The morphology and structures of the synthesized Co/C3N4 NTs nanocomposite were analyzed by comprehensive characterization methods. The effects of Co loading content on the visible-light-induced photocatalytic hydrogen production rate were studied. Our results show that this metal-semiconductor heterojunction effectively enhances the separation of photogenerated electron-holes. After 2 h of visible light irradiation, the optimal hydrogen production was obtained when the Co loading was 5%(w/w), and the hydrogen production rate was 1.7 times that of pure C3N4 NTs. | |
