Tungsten‐Boosted Erbium Oxide–Graphene Nanoplatelet Electrode for Voltammetric Determination of Metaproterenol
In this study, an electrochemical sensor was developed by modifying a glassy carbon electrode (GCE) with a nanostructured composite of graphene nanoplatelets (GNPs), ultrasound‐assisted synthesized erbium oxide (Er 2 O 3 ), and tungsten (W) nanoparticles. The platform (W@Er 2 O 3 ‐GNPs/GCE) exhibited favora...
