In this project, we are investigating the performance of recently developed graphene sponge electrodes for the degradation of organic contaminants known to be persistent to chemical oxidation (e.g., pesticides, X-ray agents), as well as other emerging pollutants (e.g., antibiotics). The major advantage of our electrodes is that they do not form any chlorine, chlorate or perchlorate, thus overcoming the major limitation of other, commercially available electrode materials - formation of toxic chlorinated byproducts. In addition, graphene-based sponge electrodes are produced using a low-cost, bottom-up synthesis method that allows easy incorporation of different 2D materials, atoms, metal oxides and others. Thus, it is possible to easily tune their surface properties and electrocatalytic activity, and design them to be reactive towards a particular set of pollutants. We have recently submitted an EU patent application and are hoping to see our material being applied in electrochemical water treatment soon!
