| 摘 要： | 本文通过简单的溶剂热法制备了g-C3N4与高比表面积的TiO2复合材料，该方法操作简单且能耗低. 甲基橙降解实验结果表明，高比表面积的TiO2有效提高了光催化活性. 光电化学测试结果表明，与g-C3N4复合后，TiO2的电荷载流子迁移速率得到明显改善. g-C3N4/高比表面积-TiO2的光催化活性很强，在100分钟内，6%-g-C3N4/高比表面积-TiO2对甲基橙的降解程度可达92.44%. 6%-g-C3N4/高比表面积-TiO2不仅具有良好的光催化降解性能，还具有较高的稳定性. 本文对6%-g-C3N4/高比表面积-TiO2的光催化机理也进行了系统的研究.

| Abstract: | g-C3N4 coupled with high specific area TiO2 (HSA-TiO2 ) compos-ite was prepared by a simple solvothermal method, which was easy to operate with low energy consump-tion. Degradation of methyl orange test results showed that HSA-TiO2 effectively improved the photocatalytic activity effectively. Photoelectrochemical test results indicated that the separation of photo-generated carriers and the charge carrier migration speed of TiO2 were improved after combination with g-C3N4. g-C3N4/HSA-TiO2 showed strong photocatalytic ability. The degree of degradation of methyl orange by 6%-g-C3N4/HSA-TiO2 could reach up to 92.44%. Furthermore, it revealed good cycle performance. The photocatalytic mechanism of g-C3N4/HSA-TiO2 was proposed. |
