Micelle confined mechanistic pathway for 4-nitrophenol reduction

Journal of Colloid and Interface Science, 2017
The model 4-nitrophenol reduction has been carried out by different groups in presence of metallic or even non-metallic catalyst elaborating different mechanistic aspects. In the present investigation, we have thoroughly studied the hydrogenation of 4-nitrophenol in a completely metal free homogeneous condition.

Stable and recyclable Au ₂₅ clusters for the reduction of 4-nitrophenol

Chem. Commun., 2013
Thiol-stabilized Au(25)L(18) monolayer protected clusters (MPCs) were found to be active for the reduction of 4-nitrophenol. Results suggest that these MPCs are stable catalysts and do not lose their structural integrity during the catalytic process. High stability under the reaction conditions enables the recyclability of these MPCs.

Polarographic reduction of nitrophenols and nitroanilines in aqueous tetrahydrofuran

Proceedings of the Indian Academy of Sciences - Section A, 1976
The reduction of nitrophenols and nitroanilines at dme has been investigated in tetrahydrofuran-aqueous buffer mixtures under varying conditions. These compounds undergo reduction through various stages and the number of waves, their half-wave potentials and relative heights have been found to be a function of composition of the solvent, pH of the ...
