PV Supplied Electrochemical Production of Hydrogen Peroxide: A Green Pathway for Fenton Based Advanced Oxidation Processes

Abstract

Hydrogen peroxide is the common reagent of the Fenton Based advanced oxidation processes, it is generally added in stochiometric yields to the Fenton catalyst (Ferrous or ferric ions) to produce hydroxyl radicals. In the present study, a green technique for the in-situ production of hydrogen peroxide is examined numerically, using modelling and simulation, based on PV supplied electrochemical process and carbon-based electrodes. The PV supply model is based on Maximum Power Point Tracking using ET-Solar M53640 panel, while the modelling of the performance of the electrochemical cell is based on an electrical equivalent schema of activation, ohmic, and concentration resistances. Two production pathways of hydrogen peroxide under acidic conditions are considered, namely the reduction of O2 and the oxidation of H2O. The performed simulations under 3 scenarios of solar radiation (low, middle and high) demonstrated that 300 W/m2 of incident global radiation results in 0.35 A of feeding current, against 0.88 A under 600 W/m2 and 1.41 A under 900 W/m2. Simulations for hydrogen peroxide production under the three scenarios have been compared based on the O2 reduction pathway, which is proved to be more performant, especially with the lower H2O2 cathodic decomposition.
