With the rapid development of industries, the emission of volatile organic compounds (VOCs) produced by various chemical projects has been deteriorating the surrounding ecological environments and health of human being. Photocatalysis is an economic approach to solve environmental problems by using light irradiation to kick off chemical reactions under the action of photocatalysts. Owing to a narrow band gap, suitable redox potential, and high chemical stability, graphite carbon nitride (g-C3N4) has been widely adopted for performing cost-effective photocatalysis. However, the rapid recombination of electrons (e−) and holes (h+) on pure g-C3N4 leads to its poor photocatalytic activity. To alleviate this shortcoming, g-C3N4 has been reported in composite form (doped with other nanomaterials: carbon, metal, oxide, ion doping etc.) Herein, we review detail research progress of four g-C3N4-based photocatalytic nanocomposites for the degradation of VOCs. Finally, we propose a scope for future research work for fabricating advanced g-C3N4-based heterostructure composite photocatalysts to treat VOCs admission.

用于光催化降解 VOC 的 g-C3N4 基纳米复合材料:综述
随着工业的快速发展,各类化工项目产生的挥发性有机化合物(VOCs)的排放不断恶化着周围的生态环境和人类健康。光催化是利用光照射在光催化剂的作用下引发化学反应来解决环境问题的一种经济方法。由于窄带隙、合适的氧化还原电位和高化学稳定性,石墨碳氮化物(gC 3 N 4)已被广泛用于执行具有成本效益的光催化。然而,纯gC 3 N 4上电子(e - )和空穴(h + )的快速复合导致其光催化活性较差。为了缓解这一缺点,人们报道了复合形式的gC 3 N 4 (掺杂其他纳米材料:碳、金属、氧化物、离子掺杂等)。在此,我们回顾了四种基于gC 3 N 4的光催化纳米复合材料VOC 的降解。最后,我们提出了未来研究工作的范围,以制造先进的 gC 3 N 4基异质结构复合光催化剂来处理 VOC 进入。
