TL;DR: Simultaneous nitrobenzene and phenol wet air oxidation was investigated in a stainless autoclave and the presence of phenol in the reaction media greatly improved the removal efficiency of nitro Benzene.

TL;DR: Results show that nanogoethite crystals can form rapidly by heterogeneous Fe( II) oxidation, and formation of goethite can profoundly influence contaminant reduction rates by Fe(II).
Abstract: Ferrous iron [Fe(II)] bound to mineral surfaces has been shown to reduce several important groundwater contaminants, but little is known of the nature of the newly formed, insoluble ferric iron [Fe(III)] and whether it influences the heterogeneous contaminant reduction process To explore how the formation and evolution of the Fe oxidation products influences contaminant reduction, we measured the kinetics of nitrobenzene reduction by Fe(II) sorbed on α-Al2O3 while simultaneously characterizing the Fe oxidation product with Mossbauer spectroscopy and electron microscopy After a brief period of slow kinetics, the onset of nitrobenzene reduction coincided with a change in particle suspension color from white to yellow-ocher due to formation of nanogoethite rods (α-FeOOH) from oxidation of sorbed Fe(II) Formation of nanogoethite on the α-Al2O3 particles appears to promote the rapid reduction of nitrobenzene Our results show that nanogoethite crystals can form rapidly by heterogeneous Fe(II) oxidation, and

TL;DR: A four-step model for nitrobenzene reduction by Fe(II) associated with iron oxides is proposed and it is proposed that magnetite>goethite>hematite>Fe(II)-humic acid complexes did not present reduction capability of nitro Benzene.

TL;DR: In this article, a polymer-supported monometallic palladium catalyst, PVP-PdCl2, is used to catalyze the hydrogenation of nitrobenzene top-aminophenol and aniline.
Abstract: In acidic reaction medium, polymer-supported monometallic palladium catalyst, PVP-PdCl2 [(PVP=poly(N-vinyl-pyrrolidone)], is used to catalyze the hydrogenation of nitrobenzene top-aminophenol and aniline. The addition of a second transition metal compound or a very small amount of 2-mercaptopyrimidine gives rise to an increase in the selectivity forp-aminophenol.

TL;DR: In this article, a case study reaction of nitrobenzenereduction was taken as the case study for this investigation, where Pt and Cu nanoparticles, supported by multiple wall carbonnanotubes, were taken as electrocatalysts and ethanolic and acidity-enhanced environments were studied as possible reaction media.
