Nano-crystalline graphite disposable electrodes for polycyclic aromatic hydrocarbons sensing

Project duration:
22/06/2022 - 21/06/2024
Project budget: 598.795 RON
Domain project: Eco-nano-technologies and advanced materials


This project has the objective to develop electrochemical sensors for polycyclic aromatic hydrocarbons (PAHs), based on nano-crystalline graphite (NCG) films deposited via plasma-enhanced chemical vapor deposition (PECVD) on different insulating substrates. The design of these electrochemical sensors includes the growth of the NCG material in a 3D nanoarchitecture as graphite nanowalls (GNW) onto the substrates of choice, increasing the active surface area in order to enhance the sensitivity towards PAHs. Carbon-based electrodes have already been employed in applications as electrochemical sensors as they allow wider working potential windows and lower noise, compared to those of metal electrodes (e.g., Au, Pt). Using PECVD as the preparation method of the NCG films, we aim to obtain 3D doped nano-crystalline graphite films with excellent electrochemical performance for the detection of PAHs.
