Deciphering the mechanistic insights of 4-nitrophenol reduction catalyzed by a 1D–2D Bi2S3 nanostructured catalyst

An anisotropic 1D-2D Bi 2 S 3 nanostructured catalyst is developed for 4-nitrophenol (4-NP) reduction and highlighted the critical roles of water as proton source and adsorbed/absorbed hydrogen species on the catalyst surface in 4-NP reduction.
