Multifunctional chemically modified electrodes with mixed cobalt phthalocyanine/nafion coatings

Electrochemical Capacitive Behaviour of Multiwalled Carbon Nanotubes Modified with Electropolymeric Films of Nickel Tetraaminophthalocyanine

“…Metallophthalocyanine (MPc) complexes are well known for their efficiency as sensors [9] and in photochemical [10,11] and electrocatalytic and electroanalytical applications [12][13][14][15][16][17][18]. The use of carbon nanotubes (CNTs) incorporated with MPc complexes in electrochemistry is gaining some attention [19,20].…”

Chemically modified carbon paste electrodes in voltammetric analysis

“…Finally, another aspect will be sketched briefly-that of multifunctional chemical modification. This type, already applied successhlly to other solid electrodes by Wang [ 173) and discussed by the author [ 1081, implies the addition of more than one modifier to the electrode material, which will then perform different functions on the components o f the analyte, ( e g , preconcentration and catalytic action). Hulk modification of CPEs is particularly attractive for obtaining multifunctional surfaces.…”

Electroanalysis with electrodes modified by inorganic films

“…The resulting electrode was well-suited to flow injection amperometry and general voltammetry. Wang and Li produced a composite of CoPC with Nafion that accomplished preconcentrations, which were preferential for positivelycharged ions, as well as electrocatalysis [39]. Wang et af.…”
