摘要: Nitrogenous amorphous carbon (a-CNx) thin films were deposited by radio-frequency cathodic magnetron sputtering (13.56 MHz) on polished and etched titanium disks. While these are cheaper to prepare than commonly reported carbon-based electrodes, the usable electrochemical window in aqueous solution is within same range spans from −1.5 +1.8 V vs. SCE. The reactivity was tested using ferri-ferrocyanide redox couple as a function of preparation parameters. obtained properties allow use a-CNx for stripping electroanalysis cations water, minimizing potential solvent reactivity. Cadmium copper used test detection abilities. Better analytical (notably sensitivity linearity) compared commercial boron doped diamond electrode. Preliminary competition/interaction experiments two performed.
