摘要:
石墨相氮化碳(Graphitic Carbon Nitride,g-C3N4)因其独特的电子结构、可见光响应能力以及优异的化学稳定性,被认为是新一代最有发展前景的光催化材料之一。但原始的块体g-C3N4存在比表面积小、电子传导率低、可见光吸收能力有限、光生载流子复合速率快等缺点,极大地限制了其在光催化领域的大规模应用。为了提高g-C3N4的光催化性能并拓展其应用,科研人员进行了大量的研究工作并取得了令人振奋的进展。本文针对g-C3N4在光催化领域的研究现状,从分子结构调控、微观结构优化、助催化剂负载、半导体异质结和同质结的构建等方面概述了基于g-C3N4材料的改性方法,介绍了g-C3N4基材料在光催化分解水产氢、污染物降解、CO2还原、有机合成四个领域的应用,论述了其在光催化领域面临的机遇和挑战,并展望了其应用前景。
Abstract:
Graphitic carbon nitride (g-C3N4) is considered one of the most promising photocatalytic materials due to its unique electronic structure, visible light response, and excellent chemical stability. Whereas, the practical applications of pristine g-C3N4 in photocatalysis are still facing with huge challenges, such as poor surface area,low electronic conductivity, insufficient visible light absorption, and fast recombination of photoinduced charge carriers. Lots of research works have been carried out to improve the photocatalytic performance and extend the applications of g-C3N4, and many exciting progresses have been gained. In this work, we summarized the research status of g-C3N4 in the field of photocatalysis. The modified strategies based on g-C3N4 are discussed, including molecular structure engineering, morphology control, co-catalyst deposition, heterostructure and homostructure construction. Then, the multifunctional applications of g-C3N4 based materials in photocatalysis including H2 evolution, pollutant removal, CO2 reduction and organic synthesis are reviewed, and the opportunities and challenges for the development of high-performance g-C3N4 based materials are prospected.
