Abstract
Abstract 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.

Abstract Metal-free, ecofriendly, and low-cost nanostructured materials are needed for effective sensing applications. This paper reports Sulfur-doped-graphitic-carbon nitride (S-g-C3N4) as a metal-free and low-cost modifier for fluorine doped tin oxide (FTO) substrates (S-g-C3N4/FTO) that acts as the working electrode for the electrochemical detection of highly toxic hydrazine. Owing to the adverse effects of hydrazine on the human and environment, it can be a potential danger and require atten...

Development of advanced materials with a benign environmentally friendly approach for heterogeneous visible light photocatalysis is always preferable. An environmentally favorable approach was used to anchor silver nanoparticles (Ag NPs) to tin oxide-decorated-graphitic carbon nitride (SnO2-g-C3N4) using a biofilm as a green reducing tool for the biogenic synthesis of 1–6 mM Ag@SnO2-g-C3N4 nanostructures (NSs). The fabricated NSs were characterized using sophisticated techniques. The developed A...

In this research, graphite-like carbon nitride (g-C3N4) was prepared via a common method i.e. one-step thermal polycondensation of urea and then modified by copper (I) oxide. After that, the as-prepared g-C3N4/Cu2O composite was used as the superior catalyst for effective coupling reaction between arylaldehydes, alkynes and secondary amines in the formation of wide range of propargylamine derivatives. The new, efficient catalyst was characterized using different techniques including Fourier tran...

A quantitative conversion of nitrobenzene is achieved using n-CeO2 as solid catalyst with aniline selectivity to 93%. Further, this catalyst is also effectively used to transform wide range of nitroarenes to their respective aniline derivatives in higher con...

Abstract A green synthesized gold-catalyst (PDA-g-C3N4/Au) for highly efficient reduction of nitroaromatics by NaBH4 was proposed. Polydopamine (PDA) served as the reductant and stabilizer for AuNPs reduction, avoiding the use of chemical reductant and stabilizer that may result in secondary contamination. g-C3N4 not only acted as the support but also provided compatibility for AuNPs deposition, enhancing the stability and deposition of AuNPs, which improved the catalytic activity. Different exp...

Abstract null null Magnesium-based metal glasses (MMGs) have broad application potential as bio-implant materials because of their disordered atomic structure, fine degradability, low elasticity modulus, and high strength. However, their low plasticity and poor corrosion resistance limit their application. In the present study, Mg-Zn-Yb-Ag metallic glasses were fabricated by injecting into a copper roller. The addition of trace amounts of ytterbium (Yb) and precious metal silver significantly im...
