Nanocatalytic Assemblies for Catalytic Reduction of Nitrophenols: A Critical Review
Critical Reviews in Analytical Chemistry, 2019Nitrophenol is common carcinogenic pollutant known for its adverse effects on human beings and aquatic life. During the last few decades, the chemical reduction of nitrophenol compounds has been widely reported as the advanced removal methodology for such hazardous dyes from aqueous reservoirs.

Catalytic reduction of 4-nitrophenol by magnetically recoverable Au nanocatalyst
Journal of Hazardous Materials, 2009A novel magnetically recoverable Au nanocatalyst was fabricated by the simple adsorption-reduction of Au(III) ions on chitosan-coated iron oxide magnetic nanocarrier. Au nanoparticles with a mean diameter of 3.14 nm were well loaded on the surface of magnetic nanocarrier because chitosan layer provided an effective driving force in the formation and ...

Treatment of nitrophenols by cathode reduction and electro-Fenton methods
Journal of Hazardous Materials, 2006This 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.

Catalytic reduction of 4-nitrophenol by palladium-resin composites
Applied Catalysis A: General, 2017Abstract Catalytic reduction of 4-nitrophenol (4-NP) by palladium-resin catalysts is promising for 4-NP detoxification, in situ regeneration of the catalysts, and recycling of the products. In this study, we examined the catalytic reduction of 4-NP by Pd 0 -based catalysts supported on three neutral resins and two anion exchange resins, using ...

The electrolytic reduction of p-nitrophenol to p-aminophenol
Electrochimica Acta, 1967Abstract 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.

Polarographic reduction of nitrophenols and nitroanilines in aqueous tetrahydrofuran
Proceedings of the Indian Academy of Sciences - Section A, 1976The 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 ...

Polyethyleneimine-stabilized palladium nanoparticles for reduction of 4-nitrophenol
Transition Metal Chemistry, 2019Palladium nanoparticles (Pd NPs) have been drawing great interest as catalysts for water treatment. Herein, high molecular weight polyethyleneimine (PEI) (molecular weight: 70 kDa) was used as template to stabilize Pd NPs. PEI was incubated with disodium tetrachloropalladate, followed by reduction with sodium borohydride.

Electrochemical Reduction of M‐Nitrophenol in Buffered Aqueous Solutions
Bulletin des Sociétés Chimiques Belges, 1984AbstractA study on the electrochemical reduction of m‐nitrophenol on a mercury electrode in buffered aqueous solutions, has been carried out, focusing on the zone of potentials corresponding to the rising portion of the wave (i/iL<0.05), whose corresponding kinetic parameters allow us to suggest a reduction mechanism for each of the pH‐ranges of 0–1,
