| 摘要: 采用热聚合法和水热法相结合的方法制备了g-C3N4/SnO2复合光催化剂。利用XRD、SEM、TEM、FT-IR和UV-Vis DRS等多种测试手段对所得样品的物相结构、微观形貌和吸光特性等进行了表征。结果表明，异质结构复合光催化剂的最大光吸收边位置相对纯相SnO2发生了明显的红移，并且SnO2颗粒均匀分布于g-C3N4表面，其中最优组分（50%-g-C3N4/SnO2）光催化降解染料罗丹明B（RhB）的效率达到了纯相g-C3N4的3.78倍。 | |

| Abstract: The g-C3N4/SnO2 composite had been fabricated by the combination of hydrothermal method and thermal polymerization process in this paper. The crystal structures and morphology of various samples were characterized using XRD, SEM, TEM, FT-IR, and UV-Vis DRS. The results showed that the optical absorption edge of g-C3N4/SnO2 composites with co-effect of heterojunction had an obvious red shift to the longer wavelength in comparison with pure SnO2 and SnO2 nanoparticles were dispersing on the g-C3N4 surface well. The photocatalytic degradation properties of g-C3N4/SnO2 composites on rhodamine B (RhB) were remarkably improved under visible light irradiation, and the degradation rate of optimal 50%-g-C3N4/SnO2 composite was 3.78 times as great as that of pure g-C3N4. | |
