چکیده انگلیسی
In this study, effects of thermal treatment conditions on the capacitive deionization performance (CDI) of activated carbon cloth (ACC) electrodes have been investigated. A total of 8 different treatment conditions has been studied by systematically changing the type of gas (Ar, CO2, N2) and the treatment temperature (700, 800, 850â¯Â°C). Treated electrodes were subjected to electrochemical testing and morphological analysis in order to assess the changes in the CDI performance. Results indicated a major discrepancy between the electrochemical and the CDI performance of the treated electrodes depending on the treatment condition. For instance, electrochemical testing showed 15% improvement in charge storage for N2-treated electrodes, while CDI performance was found to decrease by 20%. On the other hand, improvements in both electrochemical (25%) and CDI performances (60%) were observed for Ar and CO2 treated electrodes. These findings indicate that different treatment conditions promote distinct charge compensation mechanisms at the electrode surface; some of which are not beneficial for salt adsorption. Moreover, results highlight the significance of selecting a suitable thermal treatment condition for achieving enhanced performance in CDI systems utilizing ACC electrodes.
