Dual-Redox Functionalized Porous Graphene for Highly Reproducible and Stable Solid-Contact Ion-Selective Electrodes
Abstract
A novel solid contact is developed through electrodeposition, co-anchoring ethyl viologen and ferrocene on porous graphene. The proposed solid-contact ion-selective electrode using this material shows large capacitance, low drift, high reproducibility, no aqueous layer, and resistance to interferents, paving the way for calibration-free application.
