Polyoxometalate adsorbed in a metal-organic framework for electrocatalytic dopamine oxidation

Abstract

A redox-active vanadium-based polyoxometalate, V₁₀O₂₈, was post-synthetically immobilized into a water-stable zirconium-based metal-organic framework, NU-902. The adsorbed V₁₀O₂₈ in NU-902 renders charge hopping in the framework in aqueous electrolytes, and the obtained V₁₀O₂₈@NU-902 can be used as a heterogeneous electrocatalyst for electrochemical dopamine sensors.
