The electrochemical studies of thin boron-doped diamond films deposited at conductive poly(lactic acid) 3D prints

The dataset contains the electrochemical characteristics of the electrodes composed of thin boron-doped diamond films coated on commercially available graphene-doped polylactide acid. The boron doping level expressed as the [B]/[C] ratio in the gas phase for these studies was 500 and 10,000 ppm.
Cyclic voltammetry and electrochemical impedance spectroscopy were used to determine electrode kinetics, in 1 mM K3[Fe(CN)6]/1 mM K4[Fe(CN)6] redox couple containing 0.5 M Na2SO4 Cyclic voltammetry was conducted for chosen scan rates ν (5, 10, 25, 50, 75, 100, 150, 200, 300 mV s−1). EIS measurements were performed across a frequency range from 0.05 Hz to 100 kHz at a formal potential (held for 20 min) with six points per frequency decade and a perturbation amplitude equal to 10 mV.
Differential pulse voltammetry was performed to determine trinitrotoluene limits of detection in electroanalysis. The measurements were done in a 0.1 M phosphate buffer solution (PBS) of pH = 6.8 consisting of 0.064, 0.125, 0.25, 0.5, 1.0, 2.0, 4.0, 8.0, 16.0, 32.0, and 64 ppm of TNT.
The selected measurements were utilized when preparing the manuscript published in Microchimica Acta: DOI 10.1007/s00604-022-05371-w
