Recent development in exfoliated two-dimensional g-C₃N₄ nanosheets for photocatalytic applications

Abstract

In this review, the relatively systematic description of g-C3N4 nanosheets for photocatalysis is presented for the first time.

Facile synthesis of g-C3N4 nanosheets loaded with WO3 nanoparticles with enhanced photocatalytic performance under visible light irradiation

“…Among all the strategies, coupling with other semiconductors is an efficient attempt to solve above two questions due to the suitable band position and enhanced hole-electron pairs transfer between the two semiconductors by appropriate combination style. Especially, g-C 3 N 4 nanosheets which show distinct physical and chemical features with larger specic area and outstanding electronic mobility, 20,21 are considered to be an appropriate candidate to couple with other semiconductors to form high-performance photocatalysts. As a matter of fact, many progresses have been made on g-C 3 N 4 nanosheets based composites, 22 25 MoS 2 /g-C 3 N 4 , 26 etc.…”

Room-temperature synthesis of nanoporous 1D microrods of graphitic carbon nitride (g-C3N4) with highly enhanced photocatalytic activity and stability

“…Despite its many outstanding properties, the photocatalytic performance of g-C 3 N 4 is severely restricted by a low electronic conductivity, a high rate of photogenerated electron-hole pairs, and a low surface area. Hence, various approaches have been explored and adopted to overcome these problems, such as the fabrication of heterojunctions, sensitization with metal nanoparticles, doping with metallic and non-metallic elements, variation in C and N percentages, delamination of the layered structure, and control of the morphology20212223242526272829.…”

2D/2D Graphitic Carbon Nitride (g-C3N4) Heterojunction Nanocomposites for Photocatalysis: Why Does Face-to-Face Interface Matter?

“…To overcome these bottlenecks, modification of bare g-C3N4 such as nanostructure design (Niu et al, 2012;Liang et al, 2015c;Zheng et al, 2015), intercalation with Li + and Cl − (Liang et al, 2015a), elemental doping Huang et al, 2015;She et al, 2016), copolymerization (Fan et al, 2016;Rahman et al, 2016), coupling with metals or noble metals (Tonda et al, 2014;Ong et al, 2015b), incorporation with other semiconductors Putri et al, 2016a;Zhang et al, 2016g;Ye et al, 2017), hybridization with metal phosphides (Pan et al, 2017;Wen et al, 2017;Yi et al, 2017;Zhao et al, 2017a,b), and many more has been widely investigated to enhance the photocatalytic efficiency for practical benefits. To date, there are a number of excellent review articles highlighting on g-C3N4-based photocatalysts ranging from materials synthesis, functionalization, and hybridization to diversified applications Dong and Cheng, 2015;Yin et al, 2015;Zhang et al, 2015a;Zhao et al, 2015;Liu et al, 2016a;Mamba and Mishra, 2016). This undoubtedly connotes the significance of this research field hitherto in the scientific community.…”
