Abstract
Determination of Dopamine in the Presence of Ascorbic Acid on Digitonin-Doped Coal Tar Pitch Carbonaceous Electrode
Highlights
Carbonaceous materials (CMs) and their hybrids have been actively pursued as electrocatalysts for electrochemical studies.[1]
The electron transfer rate of the redox probe is partially higher on the coal tar pitch (CTP)-DG surface than on the CTP and glassy carbon (GC) surfaces [Fig. 2(a)]
The anodic peak currents of the redox probes on the GC, CTP, and CTP-DG electrodes were calculated as 39.2 ± 2.3, 50.3 ± 2.7, and 87.1 ± 1.2 μA, respectively
Summary
Carbonaceous materials (CMs) and their hybrids have been actively pursued as electrocatalysts for electrochemical studies.[1] CMs such as glassy carbon (GC),(2) vitreous carbon,(3) pyrolyzed photoresist film (ppf)-coated substrates,(4) carbon nanotubes,(5) and graphene[6] are very conductive surfaces as working electrodes. CMs with natural carbon matrices including products such as plant[7] and animal[8] sources are used as next-generation electrodes. In a previous study,(11) an electrode material was synthesized from a prawn shell with enriched chitin under pyrolysis temperature. Lv et al studied the carbonization of peanut shells.[13] The untreated and pretreated shells were pyrolyzed using a tubular furnace at 600 °C. The carbonized materials were used as ultralong cycling anodes for lithium and sodium batteries
