Carbon-based electrode materials for sensor application: a review

Due to their remarkable qualities, carbon-based electrode materials have attracted a lot of interest and are considered excellent options for a variety of uses with sensors. The review provides a summary of electrochemistry and some electrochemical measurement techniques including cyclic voltammetry (CV), chronoamperometry and chronopotentiometry, electrochemical impedance spectroscopy (EIS), and cyclic potentiodynamic polarisation (CPDP). A thorough analysis of the wide range of carbon-based materials used in sensor technologies, including their structural features, electrochemical qualities, and manufacturing processes was appraised. In addition to highlighting the special physicochemical characteristics of carbon nanotubes, graphene, carbon nanofibers, and other carbon-derived materials that make them suited for sensing applications, the survey examines the developments and contributions of these materials. Additionally, the critical role that these materials play in improving the sensitivity, selectivity, and stability of sensors is covered in the review paper. Numerous sensor applications are covered in the report, such as environmental control, biomedical diagnostics, and industrial monitoring. Finally, the appraisal highlights the potential directions for more research and innovation by providing insights into the present difficulties and future opportunities in the development of sensors using carbon-based electrode materials.
