Summary: Electrochemical sensors consisting of screen-printed electrodes (SPEs) are widely used in different fields due to their inherent characteristics such as miniaturization, cost reduction, low sample consumption, compatibility with portable equipment, and disposability. The performance of SPEs is directly influenced by the quality of the material used for printing and modifying the electrodes. Various carbon nanomaterials, including graphene, carbon nanotubes, carbon black, carbon quantum dots, graphitic carbon nitride, and biochar, have been explored for the preparation and modification of SPEs, enhancing their electrochemical response and sensitivity, as well as allowing the immobilization of biological agents for biosensor manufacturing. This review provides an overview of the current use of carbonaceous nanomaterials in the context of electrochemical SPE sensors and discusses potential future directions.

Summary: Zero-emission hydrogen and oxygen production is crucial for the UK to achieve net-zero greenhouse gas emissions by 2050. Electrochemical techniques, such as water splitting with renewable energy, offer a unique approach to achieving zero emissions. However, there can be misleading improvements in the reported performance of electrocatalysts due to the use of different connection lengths in screen-printed electrodes. By using electrochemical impedance spectroscopy, the uncompensated ohmic resistance can be overcome, providing more accurate analysis.
