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

Abstract

The BiOX (X = Cl, Br, and I) catalysts demonstrate significant catalytic activity for 4-nitrophenol reduction due to in situ formation of metal-semiconductor (Bi0–BiOX) nanocomposites in the presence of NaBH4.
