Novel nano-structured Ni(Pd)/SiO2 catalytic systems doped with carbon nanotubes (CNT)
were prepared by the sol-gel method. The catalysts proved to be effective for transformation of nitroarenes
into anilines by transfer hydrogenation method with the use of hydrazine hydrate as hydrogen
donor. Elaborated catalysts provide remarkable advantages such as low metal loading, avoidance
of toxic ligands, high yields and recyclability. No significant loss of activity was observed on fivefold
use of the catalysts.
Keywords: Anilines, hydrazine hydrate, nanostructured catalysts, nitroarenes, reduction, sol-gel method, transfer hydrogenation.
