Functionalized High Surface Area Materials for Selective Capacitive Deionization

Freshwater is unavailable for roughly one out of seven people worldwide. This is partially related to the fact that 97.5% of earth's water resources are saline water having high salt concentrations. Desalination processes are used to turn saline water into drinking water. An especially efficient process is called capacitive deionization (CDI), which is based on applying an electric voltage between two electrodes made of high surface area materials. The electric voltage triggers the removal of electrically-charged species, such as dissolved salts from the water, by adsorption on the electrode surface. This proposal is concerned with the establishment of a collaboration between Canadian and German researchers in order to develop novel selective CDI materials. Such selective material can find application not only in water desalination but also in decontamination of industrial sites or as an environmental-friendly method to mine lithium. The respective research will train Highly Qualified Personnel and contributes to Canada's economic future.
