innovation catalyst is pre-reduced, their oxides ReOx40,

innovation pointFor the first time, Pt-Re, Pt-Mn and Pt-Mo bimetallic catalysts supported by mesoporous carbon/nitrogen-doped mesoporous carbons were used as catalysts for the catalytic hydrogenation of nitrobenzene to p-aminophenol. Considering that the three metals Re, Mn, and Mo are usually not completely univalent after the catalyst is pre-reduced, their oxides ReOx40, MnOx, and MoOx have a certain degree of acidity, so the catalyst itself has an acidity. It can also be used as a dual-function catalyst, avoiding the use of liquid acids and solid acids.

And the acid sites in the catalytic system are provided by metal oxides rather than the solid acids used as carriers that were commonly used in previous bifunctional catalyst studies. This will be an innovative research direction for the study of the catalytic hydrogenation of nitrobenzene to p-aminophenol.
