Abstract

g- C₃N₄ nanosheets promote the finest visible light active photocatalyst in last decay’s, owing to inexpensive, 2D nanomaterial, good stability, excellent bandgap and visible light active semiconductor material. In this paper, we prepared highly active g- C₃N₄ nanosheets from polymerization of melamine monomer. The photocatalytic behavior and elemental nature has been further analysed by using XRD, UV-DRS, FT-IR, FE-SEM and TEM spectroscopic techniques. Besides, the bandgap ranged from 2.67 eV between VB and CB for g- C₃N₄ nanosheets conforms from UV-DRS analysis. The free electrons present in π bonds of g- C₃N₄ nanosheets were absorb light energy and electron–hole charge carries formed to attack reactants. Photocatalytic application was worked in the synthesis of N-heterocycles under blue LED irradiation. g- C₃N₄ nanosheets has enormous activity for the heterocycle synthesis in short reaction time, high yield, ease recovery and reusability to next several runs without cost of its catalytic activity under blue LED medium.

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
