Catalytic activity of first row transition metal oxides in the conversion of p-nitrophenol to p-aminophenol
TLDR
The catalytic activities of first row transition metal oxides in the conversion of p-nitrophenol to p-aminophenol were investigated in this paper, where the conversion was carried out at room temperature (30°C) using aqueous sodium borohydride.Abstract:
The catalytic activities of first row transition metal oxides in the conversion of p-nitrophenol to p-aminophenol were investigated The conversion was carried out at room temperature (30° C) using aqueous sodium borohydride The reduction process was accelerated by CuO, Co 3 O 4 , Fe 2 O 3 and NiO The oxides such as TiO 2 , V 2 O 5 , Cr 2 O 3 , MnO 2 and ZnO were found to be inactive towards the conversion of the nitrophenol The active catalysts were analyzed before and after the reaction by XRD and the reduction reaction was monitored and confirmed by UV–vis, HPLC, 1 H NMR and FT-IR techniquesread more
