Recent advancements in the fabrication and photocatalytic applications of graphitic carbon nitride-tungsten oxide nanocomposites

Abstract

The present review focuses on the widely used graphitic carbon nitride (g-C3N4)-tungsten oxide (WO3) nanocomposite for photocatalytic applications. These catalysts are widely employed due to their easy preparation, high physicochemical...

Carbon nitride- and graphene-based materials for the photocatalytic degradation of emerging water pollutants

“…Therefore, highly crystalline GCNs with low surface defects have gained much interest in photocatalytic wastewater treatment in recent years. 89 Chang et al copolymerized urea with 2-aminothiophene-3carbonitrile (ATCN), followed by polymerization under a salt melt (NaCl/KCl) condition to promote charge separation and light absorption capacity. 48 They found that the composition of urea and ATCN plays a crucial role in the light absorption capacity.…”

MXene (Ti C Tx) based nanosheet photocatalysts for water remediation: challenges and recent developments

“…These electron-hole pairs can then participate in various chemical reactions on the MXene surface or with other environmental substances. This ability to initiate and facilitate chemical reactions under light exposure makes MXene a promising material for water purification, air purification, and energy conversion applications [38][39][40][41]. For example, removing antibiotics from water sources is a pressing environmental concern due to its implications for human health and ecosystem sustainability [42].…”

CdIn2S4 microspheres embedded with mesoporous Zn-doped g-C3N4 ultrathin nanosheets for efficient photocatalytic hydrogen evolution

“…Therefore, a new strategy must be designed and developed to solve this problem. 21 As the pioneer in the field of g-C 3 N 4 photocatalyst for hydrogen generation, Wang et al has continued its research and achieved a series of significant breakthroughs. 22–25 For example, the poly (triazine imide) modified with Rh/Cr 2 O 3 and CoO x cocatalysts was designed, which largely improved the charge separation efficiency and restrained the undesired backward reaction, achieving an apparent quantum efficiency of 20.2% for photocatalytic overall water splitting.…”
