Superior Performance of a MoS 2 ‐RGO Composite and a Borocarbonitride in the Electrochemical Detection of Dopamine, Uric Acid and Adenine

A MoS 2 ‐RGO composite and borocarbonitride (BC 5 N) have been used as electrodes to selectively detect dopamine and uric acid in the presence of ascorbic acid. Both the electrodes show excellent eletrocatalytic activity towards the detection of dopamine, the detection limits being 0.55 μM and 2.1 μ...

description A MoS 2 ‐RGO composite and borocarbonitride (BC 5 N) have been used as electrodes to selectively detect dopamine and uric acid in the presence of ascorbic acid. Both the electrodes show excellent eletrocatalytic activity towards the detection of dopamine, the detection limits being 0.55 μM and 2.1 μM in the case of MoS 2 ‐RGO and BCN respectively. MoS 2 ‐RGO shows a linear range of current over the 1–110 μM concentrations of dopamine, while BCN shows over the 2.3–20 μM range. BCN also exhibits satisfactory performance in the oxidation of uric acid with a detection limit of 3.8 μM and the linear range from 4 to 40 μM. The MoS 2 ‐RGO has also been used to detect adenine as well.
