Title: Nanoporous carbons for water desalination, why double layer overlap is a good thing
Session: Tuesday 6 October, 14:45

Abstract

Small-scale and low-energy alternatives to reverse osmosis and electrodialysis are desired for ion removal from brackish water. Water desalination using nanoporous carbons with well-developed porosity takes place upon applying a voltage difference between two electrodes separated by a spacer channel with cations being stored in the cathode and anions in the anode. Despite of many years of research on this topic the exact correlation between system performance and electrode characteristics has largely remained unknown. For direct implementation of this technology, predictive tools have to include the salt adsorption capacity and desalination rate as functions of the pore size characteristics of the carbon electrode material, as well as the geometrical measures of the electrodes. By bringing together performance data on designer carbons such as ordered mesoporous silicon carbide derived carbon (SiC-CDC), and monolith (SiC-CDC) I will show a route towards the optimization of these parameters.
