Enhancing electroanalytical performance of porous boron-doped diamond electrodes by increasing thickness for dopamine detection
Original language description
This study reports on morphological, spectral, and electrochemical characterisation of 3 BDDporous electrodes of different thickness given by a number of deposited layers (2, 3 and 5), prepared using MWPECVD on SiO2 nanofiber-based scaffolds. The effect of thickness and poly-l-lysine coating on sensing properties of dopamine in a pH 7.4 phosphate buffer media was investigated. A boron doping level of ∼2 × 1021 atoms cm−3 and increased content of sp2 carbon in electrodes with more layers was evaluated by Raman spectroscopy. CV revealed reduced working potential windows (from 2.4 to 2.2 V), higher double-layer capacitance values (from 405 to 1060 μF cm−2), enhanced rates of electron transfer kinetics and larger effective surface areas (from 5.04 to 7.72 mm2), when the number of porous layers increases.
