C, N-vacancies and Br dopant co-enhanced photocatalytic H2 evolution of g-C3N4 from water and simulated seawater splitting

Carbon-vacancy engineering approach to g-C3N4 for selective 5-hydroxymethylfurfural oxidation coupled with H2O2 production

“…3A, the C 1s spectrum can be deconvoluted into two peaks located at 284.5 eV and 293.3 eV, which are attributed to carbon in adventitious carbon (C–C) and sp 2 -hybridized carbon (N–CN) in the conjugated aromatic systems, respectively. 35 However, the intensity of the C–C peak of the Cv-CN sample is decreased, which probably implies the absence of some C atoms. In Fig.…”

Photocatalytic seawater splitting for hydrogen fuel production: impact of seawater components and accelerating reagents on the overall performance

“…46). 124 Highly crystalline/amorphous g-C 3 N 4 has been reported by Sun et al (2022) for photocatalytic seawater splitting that encourages S-scheme heterojunction. A combination of crystalline and amorphous materials is developed by the solvothermal reaction of g-C 3 N 4 produced by calcination and direct calcination of melamine.…”

Investigation of NaCl-Modified Graphitic Carbon Nitride for Efficient Biodiesel Production from Waste Oil via Transesterification: A Box–Behnken Design Approach

“…Graphitic carbon nitride (GCN) is a novel carbon-based material that can be synthesized by simple thermal polycondensation from abundant precursors, such as urea and melamine. GCN possesses unique properties and shows promising applications in the fields of environmental protection, energy conversion, , and catalytic synthesis. − Compared to other heterogeneous catalysts, this carbon-based material is considered a potential alternative catalyst due to its simple and low-cost synthesis route, as well as its environmentally friendly properties. GCN possesses a certain number of basic sites but is not enough to meet the requirement of transesterification.…”
