摘要:

多孔g-C3N4基光催化材料由于具有较高的比表面积、丰富的反应活性位点和较短的电子传递路径等特点,能较好地解决块体g-C3N4基材料存在的比表面积小、光生载流子复合快及可见光利用效率低等问题,因而具有广阔的发展前景和应用潜力。本文主要从以下方面进行综述:多孔g-C3N4基光催化材料常用的制备方法,包括硬模板法、软模板法、水热合成法、热聚合法、超分子自组装法;多孔g-C3N4基材料在光催化领域的应用,包括光解水制氢、光催化降解有机污染物、光催化去除氮氧化物和光催化还原CO2等;最后指出了当前影响多孔g-C3N4基光催化材料发展的关键问题,并对其在光催化领域的应用前景进行了展望。

Abstract:

The porous g-C3N4-based photocatalysts have broad application prospects due to their unique properties such as large specific surface area, abundant surface reaction active sites and short electron transfer pathway, which can well overcome the disadvantages as compared with the bulk g-C3N4 including low specific surface area, fast recombination possibility of photogenerated electron-hole pairs and low utilization of visible light. In the review, the general synthetic strategies applied to prepare porous g-C3N4-based photocatalyst, such as hard template method, soft template method, hydrothermal methods, thermal polymerization and supramolecular self-assembly, are briefly introduced. Besides, the potential applications of porous g-C3N4-based photocatalyst in photocatalytic water splitting, photocatalytic degradation of organic pollutants, photocatalytic CO2 reduction and photocatalytic NOx abatement are discussed in detail. Finally, several comments to the challenges and the development trends of porous g-C3N4-based photocatalyst are also prospected.
