Bi-Underpotential/PtAu-bulk co-electrodeposition and subsequent Bi dissolution for the electrocatalytic oxidation and amperometric analysis of formaldehyde

Author affiliations

Abstract

A PtAuBi-UPD composite electrocatalyst modified glassy carbon electrode (GCE) is prepared via the simultaneous underpotential deposition (UDP) of Bi and bulk deposition of Pt and Au, followed by stripping of the accessible Bi, and it shows high performance for the electrocatalytic oxidation and amperometric analysis of formaldehyde.
