Treatment of nitrophenols by cathode reduction and electro-Fenton methods

Journal of Hazardous Materials, 2006
This study deals with the degradation of various nitrophenols by cathode reduction and electro-Fenton methods. Phenols (Poh), 2-nitrophenol (2-NP), 3-nitrophenol (3-NP), 4-nitrophenol (4-NP), and 2,4-dinitrophenol (2,4-DNP) are treated and different degradation sequences are obtained.

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 Au₂₅clusters 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 ...

Carbon-Based Nanorod Catalysts for Nitrophenol Reduction

ACS Applied Nano Materials, 2019
Three-dimensional porous carbon-based materials from metal–organic frameworks (MOFs) have been proven useful in structural mechanical and catalytic applications due to the high specific surface area and excellent electron transport property. However, introducing and loading of metal catalytic sites on MOF-derived porous carbon-based materials always ...

The electrolytic reduction of p-nitrophenol to p-aminophenol

Electrochimica Acta, 1967
Abstract The depolarization of p -nitrophenol at a rotating micro-cathode at different current densities and temperatures has been studied. The influence of acid strength and pH on the reduction has been investigated. Results obtained with a copper cathode and an amalgamated copper cathode are reported.

Kinetics of decay of nitrophenol radical anions and reduction mechanism of nitrophenols in aqueous alkaline media

Electrochimica Acta, 1966
Abstract m- and p-nitrophenol radical anions have been produced by macroscale electrolysis in aqueous solutions and their decay has been followed both by ESR spectroscopy and polarography. A mechanism is proposed to account for the kinetic results, showing that the decaying radicals produce the original nitroderivative and m-hydroxylaminophenol or p ...
