摘　　要：石墨相氮化碳(g-C_(3)N_(4))作为一种新型非金属高聚物半导体,具有易于合成、无毒无害、耐酸碱腐蚀、环境亲和性好等性质。独特的层状结构赋予了其较高的比表面积,适中的禁带宽度给予了其较好的光催化性能,使得其在光催化领域受到了广泛的关注。然而,纯相g-C_(3)N_(4)存在着比表面积小、活性位点不足、载流子复合过快和氧化还原能力偏弱等缺点,制约了其光催化领域的有效应用。研究表明,使用模板诱导工艺对g-C_(3)N_(4)进行结构调控可以有效解决上述问题。综述了目前常用于制备石墨相氮化碳的模板法(即硬模板法、软模板法和生物模板法),扩展讨论了多相复合工艺的进展情况,并归纳总结了g-C_(3)N_(4)基材料在光催化降解、CO_(2)转化和制氢等方面的应用情况。As a new type of non-metallic polymer semiconductor,graphite phase carbon nitride(g-C_(3)N_(4))has the properties of easy synthesis,non-toxic and harmless,acid and alkali corrosion resistance,and good environmental affinity.The unique layered structure gives it a high specific surface area,and the moderate band gap width gives it better photocatalytic performance.However,pure phase g-C_(3)N_(4) has the disadvantages of small specific surface area,insufficient active site,rapid carrier recombination and weak redox ability,which restrict its effective application in the field of photocatalysis.Studies have shown that the structural regulation of g-C_(3)N_(4) using a template induction process can effectively solve the above problems.In this paper,the template methods commonly used for the preparation of graphite phase carbon nitride(hard template method,soft template method and biological template method)are reviewed,the progress of multiphase composite process is discussed,and the application of g-C_(3)N_(4) based materials in photocatalytic degradation,CO_(2) conversion and hydrogen production are summarized.
