EN It is shown that the addition of tetrasulfonated nickel phthalocyanine (NiTSPc) to an acidic solution of aniline results in an accelerated deposition of polyaniline (PANI) from such a solution using the electrochemical potential cycling method. The electrodeposited polyaniline includes NiTSPc to form a composite film that retains its electroactivity in a wide pH range due to the self-doping effect. The thus formed composite PANI-NiTSPc film exhibits catalytic activity toward the electrooxidation of ascorbic acid in a nearly neutral buffer (pH 7.4).
