Webb17 feb. 2024 · Moreover, the Co–N x /C-800-AT catalyst has high activity toward the transfer hydrogenation of nitrobenzene into aniline and the reductive coupling of nitrobenzene into other derivates with high yields. These processes were carried out in an environmentally friendly manner without base and ligands. INTRODUCTION WebbAt the optimized conditions, nitrobenzene could be converted completely with aniline selectivity of 95% with a nitrobenzene to glycerol mole ratio of 1 : 5. At the same time, glycerol was oxidized to form fine chemicals, including 1,3-dihydroxyacetone, glyceraldehyde, formic acid, and hydroxyacetic acid.
Webb5 sep. 2007 · The electrochemical reduction of nitrobenzene produces a variety of products, including phenylhydroxylamine (PHA), aniline (AN), azoxybenzene, azobenzene, etc., which depend on the pH and electrode materials. Among these products, aniline exhibits the lowest toxicity and best biodegradable property. Webb10 dec. 2024 · In this work, we present a theoretical study on the molecular mechanism of the photocatalytic reduction of nitrobenzene to aniline on the rutile TiO 2 (110) surface. We have studied the adsorption and conversion of nitrobenzene at both the surface Ti site and the oxygen vacancy (O v) site.
Webb16 dec. 2024 · The d-band center position of the metal catalyst is one of the most important factors for catalytic selective hydrogenation, e.g., the conversion of nitrostyrene to aminostyrene. In this work, we modulate the d-band center position of the Pt surface via H coverage manipulation in order to assess the highly efficient selective hydrogenation … Webb1 dec. 2011 · AN was the only product detected during bioelectrochemical reduction of NB (maximum efficiency 98.70 ± 0.87%), whereas in abiotic conditions nitrosobenzene was observed as intermediate of NB reduction to AN (decreased efficiency to 73.75 ± 3.2%). When glucose was replaced by NaHCO (3), the rate of NB degradation decreased …
