This study presents the preparation and characterization of few-layer black phosphorus (FLBP) chitosan electrodes by controlled electrochemical deposition of chitosan nanoparticles on FLBP-modified glassy carbon electrodes. FLBP was prepared by solvent-assisted exfoliation of bulk BP and was further modified with chitosan forming together a nanocomposite, including easy cross-linking with nanomaterials and film-forming properties. Cyclic voltammetry was employed to analyze the kinetic properties of electrodes fabricated at different electrochemical deposition durations of chitosan, revealing distinct reduction and oxidation peaks using 10 V. The electrochemical impedance spectroscopy technique was employed to further characterize the investigated FLBP-chitosan nanocomposites, which provides valuable insights into the electrode material properties. The controlled electrochemical deposition of chitosan nanoparticles on FLBP-modified glassy carbon electrodes opens up possibilities for developing a wide range of electrochemical sensors and devices for energy storage applications.
