In-situ production of H2O2 at the cathode surface via catalytic coating

A typical anodic oxidation process is based on the electrochemical oxidation of target pollutants at the anode of the electrochemical system. The process can be improved, however, via the generation of H2O2 from cathodic reduction. The in-situ formation of this oxidant (and a precursor for OH* radicals) at the cathode, results in the presence of an additional possibility for priority pollutant oxidation. The formation of H2O2 is dependent on the process conditions in the system, and very specifically, on the composition of the cathode. In general, carbonaceous cathodes are beneficial for H2O2 generation. In this research, the process will be further developed and optimized. A beneficial catalytic coating for the cathode will be designed, for the production of H2O2. Furthermore, influential parameters will be determined and optimization of the process will be carried out.
