Electrochemical properties of surface-confined films of single-walled carbon nanotubes functionalised with cobalt(II)tetra-aminophthalocyanine: Electrocatalysis of sulfhydryl degradation products of V-type nerve agents

Electrocatalytic Oxidation of Diethylaminoethanethiol and Hydrazine at Single‐walled Carbon Nanotubes Modified with Prussian Blue Nanoparticles

“…Diethylaminoethanethiol (DEAET) [1][2][3][4][5] and hydrazine (NH 2 -NH 2 ) [6][7][8][9][10][11][12][13] are well-known environmentally important molecules.…”

Insights into the surface and redox properties of single-walled carbon nanotube—cobalt(II) tetra-aminophthalocyanine self-assembled on gold electrode

“…4A and B). From the well-known electrochemical properties of cobalt (II) phthalocyanine complexes [64], [65], [66] and [67] including our previous works [38], [39] and [40], we can easily assign the redox processes II and IV of the SWCNT-CoTAPc to the ring processes Pc 2− /Pc 3− and Pc 2− /Pc 1− , respectively, while processes I and III are due to the central cobalt redox processes Co II /Co I and Co III /Co II , respectively. Aside from the covalent bonding depicted in Scheme 1, the π-π interaction between the SWCNT and CoTAPc is also possible.…”

“…Few reports [36], [37], [38], [39] and [40] have described the integration of CNT with MPc complexes, especially for sensor development [38], [39] and [40], however, until now no research group has addressed the fabrication of CNT-MPc SAMs nor their electron transport (redox) properties. In this work, we describe the first example of a selfassembled SWCNT tethered to cobalt(II)tetra-aminophthalocyanine (CoTAPc) complex (Scheme 1).…”

Probing the electrochemical behaviour of SWCNT–cobalt nanoparticles and their electrocatalytic activities towards the detection of nitrite at acidic and physiological pH conditions

“…Thus, carbon nanotubes-modified electrodes have shown interesting catalytic properties toward electrochemical processes. Recently there have been renewed interests in the preparation and characterization of carbon nanotubes/metal (CNT-M) hybrid systems as electroactive material for sensor [17][18][19][20][21][22] and catalysts [23,24] among which Co, Ni and Fe are important members of mixed-valence transition metal which have proven to have excellent properties in electrocatalysis. Studies have shown that carbon nanotubes provided a large surface for metal deposition on electrodes and thus provided a synergistic relationship for an improve electron transfer between the base electrode and the CNT-M hybrids [25][26][27].…”
