A facile and rapid method of covalently modifying the surface of graphite powders with aminophenyl groups is described. This chem. modification strategy gave bulk quantities of amino-modified C powder. 4-Nitrophenyl groups are covalently attached to graphite powder via the chem. redn. of the corresponding 4-nitrobenzenediazonium tetrafluoroborate salt using aq. hypophosphorous acid. The 4-nitrophenyl groups on the C surface are then reduced to the corresponding 4-aminophenyl groups using alk. Fe(II) ammonium sulfate solns. Electrochem. and x-ray photoelectron spectroscopic characterization is carried out at each stage of the synthesis. [on SciFinder(R)]
