A novel detection of hydrogen peroxide based on a luminescent polyoxometalate

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.
