    Abstract

    Cyclic voltammetry (CV) is an established method to study redox reactions, but unfortunately does not offer detailed insights in the (intermediate) products formed. To allow mechanistic studies of electrocatalytic reactions, we have combined a silicon internal reflection element (IRE) for attenuated total reflection infrared (ATR-IR) spectroscopy and an electrochemical microreactor into a single chip. This chip contains boron doped diamond (BDD) electrodes on an insulating layer located 5 μm above the IRE to enable the detection of short lived reaction products. With this 1.3 μL volume spectroelectrochemical chip, the reversible redox pair p-benzoquinone and hydroquinone is manipulated and analyzed successfully.
