| Abstract: | "Graphitic carbon nitride (g-C(3)N(4))-based materials are attracting attention for their unique properties, such as low-cost, chemical stability, facile synthesis, adjustable electronic structure, and optical properties. These facilitate the use of g-C(3)N(4) to design better photocatalytic and sensing materials. Environmental pollution by hazardous gases and volatile organic compounds (VOCs) can be monitored and controlled using eco-friendly g-C(3)N(4)- photocatalysts. Firstly, this review introduces the structure, optical and electronic properties of C(3)N(4) and C(3)N(4) assisted materials, followed by various synthesis strategies. In continuation, binary and ternary nanocomposites of C(3)N(4) with metal oxides, sulfides, noble metals, and graphene are elaborated. g-C(3)N(4)/metal oxide composites exhibited better charge separation that leads to enhancement in photocatalytic properties. g-C(3)N(4)/noble metal composites possess higher photocatalytic activities due to the surface plasmon effects of metals. Ternary composites by the presence of dual heterojunctions improve properties of g-C(3)N(4) for enhanced photocatalytic application. In the later part, we have summarised the application of g-C(3)N(4) and its assisted materials for sensing toxic gases and VOCs and decontaminating NOx and VOCs by photocatalysis. Composites of g-C(3)N(4) with metal and metal oxide give comparatively better results. This review is expected to bring a new sketch for developing g-C(3)N(4)-based photocatalysts and sensors with practical applications" |
