Carbon nanofibers (CNFs) have been successfully prepared by using electrospinning at various flowrates, and were formed from polyvinyl alcohol (PVA) and activated carbon (700-1400 m2/g) as electrodes on capacitive deionization. Before being furthermore deposited into electrodes, characterization was carried out on CNFs by using SEM. Cyclic voltammetry analysis was also performed to determine the electrolysis mechanism of the electrodes. The best results in removing salt reaching 70% were achieved by capacitive deionization systems with the smallest diameter size of CNFs, at a voltage of 1.5 V. The CNFs formed by electrospinning have potential to be used as excellent capacitive deionization electrodes for the desalination process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
