Abstract An improved method for the preparation of g-C3N4 is described. Currently, heating (>400 C°) of urea is the common method used for preparing the g-C3N4. We have found that sonication of melamine in HNO3 solution, followed by washing with anhydrous ethanol, not only reduce the crystallite size of g-C3N4 but also facilitate intriguing ...

Graphitic carbon nitride (g-C3N4), a highly stable wide bandgap material, is yet to be evaluated for thin-film applications in devices since its basic electrical properties are not understood. We study its vacuum-deposited thin film form, and in combination with Al2O3, in sandwiched devices using capacitance–voltage (C-V) and current–voltage (I-V ...

Novel g-C3N4/g-C3N4 S-scheme isotype heterojunction for improved photocatalytic hydrogen generation
Applied Surface Science, 2019Abstract Rationally designing heterostructure is a promising way to promote the charge carrier separation of intrinsic photocatalysts, thus contributes the improvement of solar to chemical energy conversion. Herein, a novel isotype heterojunction consisted of MCN and UCN, respectively derived from hydrothermally-treated melamine and urea, was ...

The exploration of metal-free catalyst g-C3N4 for NO degradation
Journal of Hazardous Materials, 2021We propose a new metal-free scheme of the reaction between the molecules CO and NO on a g-C3N4 monolayer. We first investigate the electronic properties of the related molecules CO, NO, N2, and CO2 adsorbed g-C3N4 systems, and then figure out the possible reaction pathways.

Abstract Mesoporous g-C3N4/g-C3N4 (Meso-g-C3N4/g-C3N4) nanosheets laminated homojunctions have been fabricated via template-calcination strategy using melamine and amino cyanamide as co-precursors. The prepared Meso-g-C3N4/g-C3N4 nanosheets laminated homojunctions possess relative high surface area of 34 m2 g−1, large pore size of 15.0 nm and narrow ...

Barley malt, the main raw material for beer production, is at risk of Fusarium graminearum (F. graminearum) infection, leading to the possible production of large amounts of deoxynivalenol (DON) in malt. DON in malt can migrate into the final beer product, posing a food safety risk to consumers. In our work, a protonated g-C3N4/oxygen-doped g-C3N4 (CNH/

Abstract The effect of g-C3N4 on the sensing performance of a Pt/g-C3N4/ polythiophene nanocomposite (Pt/g-C3N4/PTh NCs) was investigated in this work. The nanocomposites were synthesized via the chemical reduction of Pt (II) in the presence of l -cysteine as the reducing agent.
