Electrocatalytic properties of Cu–Zr amorphous alloy towards the electrochemical hydrogenation of nitrobenzene

Insights into the mechanism of nitrobenzene reduction to aniline over Pt catalyst and the significance of the adsorption of phenyl group on kinetics

“…Experimentally, over a range of catalysts studied, only nitro-group of nitrobenzene was reduced to amino group whilst the phenyl group held, therefore we concentrated on the reduction mechanism of nitro-group in this theoretical study [1][2][3][4][5][6][7][8][9][10][11][12][13]. In the surface catalytic reactions, the first stage was the adsorption of nitrobenzene on the Pt(111) surface.…”

“…Aniline is manufactured via catalytic hydrogenation of nitrobenzene (C 6 H 5 NO 2 ) over a series of transitional metal catalysts such as Pd, Pt, Ni, Cu, Ru and Au, at various conditions, e.g., gas-phase or liquid-phase hydrogenation, as well as electrochemical reduction [1][2][3][4][5][6][7][8][9][10][11][12][13]. In the catalytic hydrogenation of nitrobenzene, the nitro group is usually reduced to amino group but the phenyl group remains [1][2][3][4][5][6][7][8][9][10][11][12][13]. A wide range of catalysts for reduction of nitrobenzene to aniline have been studied experimentally.…”

Corrosion Resistance and Electrocatalytic Properties of Metallic Glasses

“…Some investigations about the electrocatalytic activity of metallic glasses for the hydrogen evolution reaction or oxygen reduction reaction, such as Co- [108,109], Zr- [110,111], Ni- [113], Cu- [114], Pt- [115,116], and Au-based [117] metallic glasses, are done in last few decades. However, Febased metallic glasses are the most attractive as catalytic material.…”

Promotion of the electrochemical hydrogenation of nitrobenzene at hydrogen storage alloys studied using a solid electrolyte method

“…Extensive investigations of the electrochemical reduction of nitrobenzene on Cu electrodes in aqueous acidic solutions [10,11] and polymer electrolytes [12][13][14] have suggested that the nitrobenzene reduction is a totally irreversible reaction under diffusion control. Cyclic voltammograms for the nitrobenzene reduction are characterized by a single cathodic current peak proportional to the square root of scan rate during the negative-going scan and no any peak is observed during the reverse scan.…”
