| 中文摘要: |
| 在当前能源短缺和环境污染的背景下,光催化分解水制氢和光催化污染物降解技术展现出解决能源与环境问题的巨大潜力。石墨相氮化碳(g-C3N4)因其易获得、稳定性良好、具有适宜的禁带宽度和能带位置等优点在光催化领域展现出广阔的前景。但纯g-C3N4由于比表面积较低、光生载流子复合率高等问题,导致光催化效率受限。研究表明,将g-C3N4与其他半导体材料复合可以有效的解决光生电子空穴对的复合问题,并显著提高比表面积,大幅提升光催化活性。本文综述了石墨相氮化碳与金属硫化物、金属氧化物等半导体材料复合并在光催化产氢和污染物降解方面应用的研究进展,以期推动基于g-C3N4的复合光催化剂的蓬勃发展。 |
| 英文摘要: |
| In the context of today"s energy shortages and environmental pollution, the technologies of photocatalytic hydrogen production from water splitting and photocatalytic pollutant degradation have shown great potential in addressing energy and environmental problems. Graphitic carbon nitride (g-C3N4) has shown a promising future in the field of photocatalysis due to its advantages such as easy availability, good stability, suitable bandgap, and appropriate band positions. However, the photocatalytic efficiency of pure g-C3N4 is limited by issues such as low specific surface area and high recombination rate of photogenerated charge carriers. Studies have shown that combining g-C3N4 with other semiconductor materials can effectively suppress the recombination of photogenerated electron-hole pairs, significantly increase the specific surface area, and greatly enhance photocatalytic activity. This article reviews the research progress on the composite of g-C3N4 with semiconductor materials such as metal sulfides and metal oxides, and their applications in photocatalytic hydrogen production and pollutant degradation, aiming to promote the vigorous development of g-C3N4-based composite photocatalysts. |
