Enhanced reduction of p-nitrophenol by zerovalent iron modified with carbon quantum dots
, 2021The pollution of aromatic nitro compounds in water is a critical issue, and the reduction of p-nitrophenol (p-NP) by the combination of catalyst/reductant has been a hot topic in recent years. The methods reported previously bore several defects, such as

Enzymatic oxidation of p-nitrophenol
Biochemical and Biophysical Research Communications, 1979Abstract A Moraxella sp. capable of growth with p-nitrophenol was isolated from activated sludge. Differential centrifugation of crude cell extracts gave a membrane preparation that oxidized p-nitrophenol to hydroquinone and nitrite. Enzymatic activity was dependent on the presence of oxygen and reduced pyridine nucleotides and was stimulated by the ...

Slow adsorption and dissociation kinetics of NaBH4 onto the catalyst surface limit the hydrogenation reduction of hazardous p-nitrophenol to worthy p-aminophenol. Herein, we design a mineral-modulated catalyst to facilitate the rate-limiting step. Carbon-

A novel biosensor-based method for the detection of p-nitrophenol in agricultural soil.
Chemosphere, 2022Directly measurement of the bioavailable concentration of soil contaminants is essential for their accurate risk assessment. In this study, we successfully modified and identified the key genetic elements (pobR1-3) for the bio-detection of p-nitrophenol ...

Biodegradation of p-nitrophenol by P. putida
Bioresource Technology, 2006A strain of Pseudomonas putida was found capable of metabolizing p-nitrophenol (PNP) as a sole source of carbon, nitrogen and energy. To explore the applicability of this strain for bioremediation for controlling environmental PNP pollution, its degradation potential at 300 and 500 ppm was examined in a medium devoid of carbon and nitrogen source ...

Abstract Single crystals of Dimethylammonium p-nitrophenolate–p-nitrophenol have been grown from aqueous solution by slow evaporation solution growth technique. Unit cell parameters of the grown crystal were confirmed by single crystal X-ray diffraction analysis and the synthesized compound is crystallized in monoclinic system.
