| 摘 要： | 采用二次凝胶-溶胶法和水热法合成了具有光催化效应的GNR-TiO_2/g-C_3N_4异质结构,并对其性能进行了研究.研究结果表明:GNR-TiO_2/g-C_3N_4异质结构表现出强的光催化活性,并在可见光照射下,对有机物亚甲基蓝有良好的催化效果.这主要归因于石墨烯纳米带作为载体,不仅增加了异质结构的比表面积,还使空穴-电子对的再结合率降低.

| Abstract: | An efficient strategy for synthesis of GNR-TiO2/g-C3N4 heterostructure photocatalyst is demonstrated using a combining sol-gel and hydrothermal method and its chemical properties are studied.The GNR-TiO2/g-C3N4 heterostructure shows enhanced photocatalytic activity for degradation of MB under visible light irradiation.The increased photocatalytic activity of GNR-TiO2/g-C3N4 composites can be attributed to forming a larger number of interfaces,separating the electron-hole pairs more efficiently. |
