Reduction of 4-nitrophenol catalyzed by nitroreductase

Chinese Chemical Letters, 2007
Abstract The reduction of 4-nitrophenol catalyzed by nitroreductase in the presence of NADH was investigated in this paper. 4-Amino-phenol and 4-hydroxylamino-phenol were found in the reductive products. The relationship between reaction time and the reductive ratio were studied.

Catalytic reduction of 4-nitrophenol by magnetically recoverable Au nanocatalyst

Journal of Hazardous Materials, 2009
A 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 ...

Pd nanoparticles anchored Co-MOF for nitrophenol reduction

Environmental Science and Pollution Research, 2023
Three nitrophenols are among the 126 priority toxic pollutants identified by the US Environmental Protection Agency. Catalyzing hydrogenation is a simple way to convert these toxic nitrophenols into harmless aminophenols. Commercial PdC has excellent catalytic hydrogenation activity but has weaknesses such as high price and low reusability.

Carbonylative Reduction of Nitrophenols to Aminophenols

Collection of Czechoslovak Chemical Communications, 1995
Two- or three-component catalysts composed of (i) sulfur or sulfur compound (H2S, CS2, COS, Na2S), (ii) basic additive (triethylamine, CH3ONa, Na2S), and usually (iii) vanadium(V) compounds (e.g. NH4VO3) were found to catalyze efficiently the reaction of CO + H2O with isomeric nitrophenols to give the corresponding aminophenols.

Reduction of nitrophenols in an electrocatalytic system

Russian Journal of Applied Chemistry, 2009
Results of research into hydrogenation of o- and p-nitrophenols in an electrocatalytic system on a cathode activated with d- and s-metal catalysts are presented. The optimal conditions for o-aminophenol formation on Raney nickel were identified by the probability-determined method for the experimental design.

Nanocatalytic Assemblies for Catalytic Reduction of Nitrophenols: A Critical Review

Critical Reviews in Analytical Chemistry, 2019
Nitrophenol 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.
