Voltammetric Determination of H2O2 Using a GC-LDH-Proline Catalytic Sensor

In our recent work, we built a new catalytic sensor for the determination of hydrogen peroxide, consisting of a glassy carbon (GC) electrode, on which it was glued, by means of a layer of silver paste, a nanomaterial of the type “Layered Double Hydroxide” (LDH), with formula that can be briefly expressed as [ZnIIAlIII (OH)2]+ NO3− $$\cdot$$ n H2O. We have ascertained experimentally that the response of this sensor can be improved if proline is present in the buffer solution.
