Derivative voltammetry: a simple tool to probe reaction selectivity in photoelectrochemical cells

We demonstrate the use of the derivative voltammogram method to predict the selectivity of the photo-driven oxidation of 5-hydroxymethylfurfural (HMF) on a WO3 photoanode as a function of applied potential using only information obtained from the linear sweep voltammogram (LSV). This method can be a simple tool to gain an insight into reaction selectivity in photoelectrochemical cells.
