Magnetic graphene noble metal aerogels: preparation and application for catalytic degradation of 4-NP

Abstract

In this work, the preparation of magnetic graphene noble metal aerogels(GA-Fe3O4-Au-ethanol) was realized by self-assembly induced by radiation reduction. The prepared material GA-Fe3O4-Au-ethanol can be easily attracted by the magnet....

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

“…Recent studies show that direct hydrogenation of 4-NP catalyzed by non-noble metals is considered an alternative process for the production of 4-AP. 26–29 However, different non-noble metal-based catalysts have been studied and investigated for their mechanisms toward 4-NP reduction. 30 Among them, bismuth-based compounds, including bismuth oxychloride (BiOCl), bromide (BiOBr), and iodide (BiOI), have emerged as noteworthy candidates in the field of photocatalysis.…”
