Abstract
The electroformation of the tetrasulfonated nickel phthalocyanine (NiTSPc) film in alkaline solution onto carbon fiber microelectrode is investigated in order to improve the electrochemical detection of nitric oxide (NO) in solution. We compare in this study the sensitivity of a carbon fiber microelectrode coated by nickel phthalocyanine deposited either by cyclic voltammetry or by controlled potential electrolysis at +1.2 V/SCE with a previously reported nickel porphyrin modified electrode. We show that the phthalocyanine film formed by cyclic voltammetry gives a modified microelectrode with a good sensitivity to NO, higher than the obtained one with nickel phthalocyanine and/or porphyrin deposited by controlled potential electrolysis.
