摘　　要：多孔g-C_(3)N_(4)光催化剂具有较高的比表面积和多孔结构,能够提供光生载流子和反应物质的运输通道以及大量活性位点用于氧化还原反应,较好地解决了块状g-C_(3)N_(4)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。综述了通过硬模板法、软模板法改善块状g-C_(3)N_(4)的结构特性,以及多孔g-C_(3)N_(4)在光催化应用领域的主要研究进展。最后总结了两种制备方法的优劣以及当前面临的关键问题和对未来的展望。Porous g-C_(3)N_(4)photocatalyst has high specific surface area and porous structure,provides transport channels for photo-generated carriers and reactants,and a large number of active sites for oxidation-reduction reaction,which can better solve the problems of small specific surface area,fast recombination of photo-generated carriers and low utilization efficiency of visible light in bulk g-C_(3)N_(4).In this paper,the structural characteristics of bulk g-C_(3)N_(4)improved by hard template method and soft template method,and the main research progress of porous g-C_(3)N_(4)in the field of photocatalysis application are reviewed.Finally,the advantages and disadvantages of the two preparation methods,as well as the current key problems and future prospects are also summarized.
