A novel detection ofhydrogen peroxide based on a luminescent polyoxometalate

Abstract

In this paper, we attempt to construct a simple and sensitive detection method for hydrogen peroxide based on reversible colour change and luminescence switching modulated by the electrochemical stimulation and redox reaction of H₂O₂ with electroreduced polyoxometalate. This method successfully combines the electrochromic and luminescent properties of the polyoxometalate to develop a novel detection method for H₂O₂ with good reversibility, which displays high sensitivity, a wide linear range and a low detection limit to H₂O₂.
