摘要
光催化技术具有合成过程简便、反应条件易控制、充分利用太阳能且无二次污染等突出优势,在处理环境污染问题和缓解全球能源短缺等方面具有广阔的应用前景.然而,由于光生载流子低的转移和分离效率,实际的光化学转换效率提升受到了限制.新兴的S型异质结光催化剂由于其在空间上实现了光生载流子的有效转移分离并展现出强的氧化还原能力,在太阳燃料制备和环境治理领域受到了广泛关注和研究.综述了异质结光催化剂的发展历程和S型异质结的基本原理及在各领域中的应用.最后,总结了S型异质结光催化剂的突出优势,并提出S型异质结光催化剂的发展前景和面临的挑战,为开发具备高效光催化活性的新型异质结光催化剂提供思路和参考.
Abstract
Photocatalytic technology has outstanding advantages such as simple synthesis process,easy control of reaction conditions,full utilization of solar energy,and no secondary pollution.It has broad application prospects in addressing envi-ronmental pollution problems and alleviating global energy shortages.However,due to the low transfer and separation effi-ciency of photo generated carriers,the actual improvement of photochemical conversion efficiency is limited.The emerging S-tpye heterojunction photocatalysts have received widespread attention and research in the fields of solar fuel preparation and environmental governance due to their effective transfer and separation of photo generated carriers in space and their strong redox power.The development history of heterojunction photocatalysts,the basic principles of S-tpye heterojunctions,and their applications in various fields were reviewed.Finally,the outstanding advantages of S-tpye heterojunction photo-catalysts were summarized,and the development prospects and challenges faced by S-tpye heterojunction photocatalysts were proposed,providing ideas and references for the development of new heterojunction photocatalysts with high photocata-lytic activity.
