Electrocapacitive desalination of brackish water using biochars

Abstract

Electrodes fabricated from porous carbons derived from biomass have been observed to be suitable for high capacity energy storage, and subsequently investigated for their effectiveness in CDI, but there is a dearth of studies to find a relationship between the electrochemical performance of the carbon and the biomass properties and process conditions. Because cellulose, hemicellulose and lignin are the main components in biomass, in this study, we produce carbons from rice hull, switchgrass and poplar wood, each representative of cellulose-rich, hemicellulose-rich and lignin-rich biomass, respectively. The investigation goal is correlating electrochemical performance of the carbon to the nature of the biomass precursor and the processing conditions. This study will aid in identifying and classifying biomass raw materials to develop carbon materials with well-defined pore structures.
