缺陷对半导体光催化剂的能带结构和性能有着重要的影响。在此,我们开发了一个一步的策略,引入缺陷的框架中的g-C3N4通过可控的共聚三聚氰胺与一系列的部分反应性封端单体。封端分子对改性g-C3N4的性能有很大的影响。所获得的缺陷g-C3N4表现出增加的表面积、提高的电荷载流子分离效率和窄的带隙以及导带的负偏移。特别地,与原始的g-C3N4相比,缺陷丰富的CN-DPT显示出10倍的用于制氢的可见光活性的改善。
Defects have a vital effect on the band structures and properties of semiconductor photocatalysts. Herein, we developed a one-step strategy to introduce defects in the framework of g-C3N4 by controllable copolymerization of melamine with a series of partially reactive end capped monomers. The capping molecules have great impacts on the properties of modified g-C3N4. The obtained defective g-C3N4 exhibits an increased surface area, improved charge carrier separation efficiency, and a narrowed band gap with a negative shift of the conduction band. Particularly, defect-rich CN-DPT shows 10 times improvement of visible light activity for hydrogen production compared with pristine g-C3N4.
