Facile preparation of a Pt-ERGO composite modified screen-printed electrode for the sensitive determination of phenolic compounds.

ABSTRACT: The mass production of screen-printed electrochemical devices with integrated electrodes has facilitated the widespread adoption of electroanalytical methods. The SPEs (screen-printed electrodes) overcome some obstacles associated with the use of conventional electrochemical cells, making them accessible to untrained operators. Despite their advantages, SPEs require activation/modification of the working electrode (WE) to enhance sensitivity. Nanomaterials, with metal nanoparticles (NPs) dispersed in polymers and/or carbon NPs has gaining popularity for this purpose. In this study, we describe a modification of carbon SPEs (SPCEs) using Pt NPs and reduced graphene oxide (ERGO). The Pt-ERGO@SPCE is prepared by galvanostatic reduction of drop-casted precursors directly onto the WE surface, e
