| 中文摘要: |
| 近年来,石墨相氮化碳(g-C3N4)作为一种具有独特能带结构、低成本、环境友好特性的材料,在光催化领域尤其是光催化水分解产氢方面展现出了巨大的潜力。然而,其固有的局限性,包括可见光吸收效率低、光生电子-空穴对复合速率快以及比表面积有限等问题,严重制约了g-C3N4的光催化活性。对石墨相氮化碳进行元素掺杂能够有效缩小带隙,提高对光的吸收能力,抑制光生电子-空穴对复合,显著改善光生载流子的利用效率,因此成为了光催化领域的研究热点。本文综述了近几年对石墨相氮化碳元素掺杂改性的多种策略,及其在光催化水分解产氢领域的研究进展,以期助力石墨相氮化碳在光催化领域的快速发展。 |
| 英文摘要: |
| In recent years, graphitic carbon nitride (g-C3N4), as a material with unique band structure, low cost andenvironmental friendliness, has shown great potential in the field of photocatalysis, especially in that of photocatalytic water splitting to produce hydrogen. However, its inherent limitations, including low visible light absorption efficiency, fast photogenerated electron-hole recombination rate, and limited specific surface area, seriously limit the photocatalytic activity of g-C3N4. Elemental doping of graphitic carbon nitride can effectively narrow the band gap, improve the absorption capacity of light, inhibit the photogenerated electron-hole pair recombination, and significantly improve the utilization efficiency of photogenerated carriers, so it has become a research hotspot in the field of photocatalysis. In this paper, we summarize various strategies for doping and modifying graphitic carbon nitride in recent years, and their research progress in the field of photocatalytic water splitting to produce hydrogen, in order to promote the rapid development of graphitic carbon nitride in the field of photocatalysis. |
