A multiwalled carbon nanotube/tetra-β-isoheptyloxyphthalocyanine cobalt(ii) composite with high dispersibility for electrochemical detection of ascorbic acid

Multielectrocatalysis by Layer-by-Layer Films Based on Pararosaniline and Vanadium-Substituted Phosphomolybdate

“…This value is comparable to that reported for modified electrodes with MWCNT/poly(NileblueA) (1.6 × 10 −6 mol dm −3 ) 56 57 Comparisons between the catalytic peak currents for a specific ascorbic acid concentration also show good results for the {PR/ PMo 11 V} 4 /GCE with i pa ≈ 1.13 μA for a AA concentration of 0.3 × 10 −3 mol dm −3 . Although a higher value was obtained for SiW 11 Fe@MIL-101/PGE 55 (∼4 μA), ours is higher than that for MWCNT/phthalocyanines/GCE (∼0.9 μA) 57 and [SiNi-(H 2 O)W 11 O 39 ]/cysteamine/gold electrode (∼0.25 μA).…”

Systematic study of transition-metal (Fe, Co, Ni, Cu) phthalocyanines as electrocatalysts for oxygen reduction and their evaluation by DFT

“…60 nm compared with the Q band of FePc, attributed to the charge transfer of FePc to GCB. It indicates that the possible π-π interaction exists between FePc and the surface of GCB, 33 Besides, compared with the FT-IR spectrum of the GCB, the characteristic peaks of FePc obviously appear in the spectrum of FePc/GCB (Fig. S6).…”

Economical, facile synthesis of network-like carbon nanosheets and their use as an enhanced electrode material for sensitive detection of ascorbic acid

“…3,44 To further evaluate the analytical performance of the NCN/ GCE for AA detection, different comparison aspects including applied potential, linear range and detection limit are listed in Table 1. The proposed method exhibits better than or comparable performance to those of the previous reports, 34,[45][46][47][48] suggesting that the carbon nanosheets can be directly used as an enhanced material for sensitive determination of AA.…”
