Carbonized Polyaniline as a Catalyst for Hydrogenation with Molecular Hydrogen of Organic Substrates with C=C Double Bond and Nitro Group

Nitrogen-doped carbon, which is characterized by a large surface area and the presence of micro- and mesopores, has been obtained by pyrolysis of polyaniline (emeraldine base) in a reducing atmosphere. It is found that the surface layer of such material contains nitrogen in pyridinic, pyrrolic, and quaternary configurations, as well as hydroxyl and carbonyl groups. It is shown that carbonized polyaniline reveals catalytic properties in the processes of gas-phase and liquid-phase hydrogenation with molecular hydrogen of organic substrates containing C=C double bond and nitro group (ethylene, α-methylstyrene, p-nitrotoluene) are revealed.
