Facile synthesis of C30-AuNPs for the effective catalytic reduction of nitrophenols and azo dyes

Abstract

A facile and green synthesis approach of C30-AuNPs is developed for the effective catalytic reduction of nitrophenols and azo dyes, and the in-depth mechanism investigation is described by thermodynamic and kinetic analysis.

In situ synthesis of metal (Bi0)–semiconductor [BiOX (X = Cl, Br, and I)] nanocomposites as a highly effective catalyst for the reduction of 4-nitrophenol to 4-aminophenol

“…20 Currently, 4-AP is produced by the reduction of catalytic hydrogenation of 4-NP in the presence of noble metals catalysts such as Pd, Pt, Au, Ag, and so forth. 21–25 The main problem with these metal catalysts is the use of high cost and scarcity of noble metals. Therefore, developing an environmentally friendly and cost-effective catalyst for producing 4-AP is a significant challenge in the field of catalysis research.…”
