CATALYST FOR REDUCTION OF NITROARENE AND PREPARING METHOD THEREOF

摘要

PURPOSE: A catalyst for the reduction of nitroarene compounds and a manufacturing method thereof are provided to show high catalyst activation to the reduction reaction of the nitroarene compounds due to a synergic catalytic effect of inorganic nanoparticles and graphene oxide nanosheets, to provide improved catalyst stability, and to manufacture nanocomposites of inorganic nanoparticle-graphene oxide nanosheets by a single synthesis process. CONSTITUTION: A catalyst for the reduction of nitroarene compounds includes inorganic nanoparticles coated with a free ligand and graphene oxide nanosheets supporting the inorganic nanoparticles. The graphene oxide nanosheets are a reduced graphene oxide nanosheets. The inorganic nanoparticles are selected from the group consisting of metallic nanoparticles, metal oxide nanoparticles, and their composite. The free ligand is selected from the group consisting of substituted or non-substituted aminopyridine and pyridine series. The average diameter of the inorganic nanoparticle coated with free ligand is 1-20 nm. The graphene oxide nanosheet has the thickness of 0.5-1.5 nm and the length of 0.7-1.5 micrometers.
