dc.description.abstractWe present a fundamental investigation on the impact of single-walled carbon nanotube (SWCNT) on the film structure and redox behaviour of tetraaminophthalocyaninatonickel(II) complex (NiTAPc) electropolymer immobilized on a basal plane pyrolytic graphite electrode (BPPGE). SWCNT induces crystallinity on the NiTAPc electropolymeric film structure and increases its apparent electron transfer rate constant (kapp). We proved that there is potential advantage of using electrode based on the SWCNT-poly-NiTAPc hybrid for catalytic and sensing applications as it enhances the catalytic current for the detection of nitric oxide more than twice compared to bare BPPGE, BPPGE-SWCNT and other electrodes without SWCNTs.en
