| 摘要: 采用溶剂热法制备了具有二维/一维（2D/1D）纳米结构的MoS2纳米片/管状g-C3N4（MS/TCN）复合光催化剂，并在可见光照射下用于光催化海水产氢。实验结果表明MS/TCN复合材料的光催化活性优于纯相TCN。此外，MS/TCN-0.5样品（含有0.5%（w/w）的MoS2）显示出最佳的析氢活性，其产H2速率为85.1 μmol·h-1，且在进行循环性测试后，活性没有明显降低。 | |

| Abstract: In this work, the development of efficient and stable photocatalyst has been the central topic of scientific research. Herein, MoS2 nanosheets/tubular-like g-C3N4 (MS/TCN) composite photocatalysts with two dimension/one dimension (2D/1D) nanostructure were fabricated through a facile solvothermal method for photocatalytic hydrogen production from seawater under visible light irradiation, exhibiting enhanced photocatalytic performance in comparison of single MS or TCN. Among of them, MS/TCN-0.5 sample (0.5%(w/w) MoS2) showed optimum H2 evolution rate of 85.1 μmol·h-1 and possessed outstanding stability (no significant decrease after 4 cycles). The enhanced photocatalytic activity of MS/TCN composite photocatalyst can be attributed to the fact that the loading of 2D MS, as a cocatalyst, promotes the transfer of photo-induced electron and improves the separation efficiency of electron-hole pairs of 1D TCN. | |
