The Waterloo Institute for Nanotechnology Seminar Series presents
Doped Carbon and Graphene Materials for Electrochemical Applications
Dr. Edward Roberts, Professor and Associate Head Research
Department of Chemical and Petroleum Engineering

11 a.m. - 12 p.m.
All are welcome to attend.
Electrochemical technologies for energy storage and water treatment (as well as other applications) require electrode materials that are low cost but offer good performance and lifetime. Carbon materials are widely used, as they are relatively cheap and very versatile. The seminar will discuss the development of electrochemical exfoliated graphene materials and heteroatom doped carbons, considering two electrochemical applications: vanadium redox flow batteries, and adsorption combined with electrochemical regeneration for treatment of organic contaminants. Doping of carbon can be achieved by thermo-chemical treatments, and has a significant impact on the electrochemical characteristics. Exfoliated graphenes such as reduced graphene oxide are an attractive carbon material for electrochemical applications, since they offer high specific surface area, conductivity, and electrochemical activity. However, exfoliation methods are relatively complex, energy intensive and consume expensive and/or toxic chemicals. Electrochemical exfoliation offers low cost, simple process and by tuning the operating conditions the characteristics of the graphene (including heteroatom doping) so that they can be tailored for different applications.
