摘要

In the present study, in situ selenium-doped graphitic carbon nitride, showed as Se-g-C3N4, was prepared by applying low-cost melamine and 2,4,6-triselenocyanato-1,3,5-triazine as the precursor materials through a simple thermal condensation strategy and used as an ideal catalyst support. Ag NPs were anchored on the Se-g-C3N4 through the co-reduction method with NaBH4 as a reductant to fabricate the Se-g-C3N4/Ag nanocatalyst. Various microscopic and spectroscopic techniques confirmed the construction of Se-g-C3N4/Ag nanocatalyst and the obtained results have been well interpreted in the context. The Se-g-C3N4/Ag indicated excellent catalytic efficiency and exclusive chemoselectivity in the hydrogenation of nitroaromatic compounds using a green reducing agent (NaBH4) in an environmentally friendly aqueous media, and the corresponding anilines were produced as sole products. The supreme catalytic activity and durability of the Se-g-C3N4/Ag can be ascribed to the synergetic interaction between the highly dispersed Ag NPs and the support.

Mastelaro, Otaciro R. Nascimento, Dalva E. C. Ferreira, Frederico Ramos Fioravante, Marcio C. Pereira, Joao P. de Mesquita

Summary: This study demonstrates that oxygenated graphitic carbon nitride (g-C3N4) prepared at different temperatures can degrade indigo carmine with hydrogen peroxide in the dark by a reaction similar to a conventional Fenton's reaction. The Fenton-like activity is directly related to the oxygenated functional groups on g-C3N4 structure, mainly -OH functional groups, suggesting a potential alternative to traditional metal catalysts in Fenton-like reactions for advanced oxidation.
