▎ 摘　　要

Comments were made by Biesheuvel et al. on a recent publication by Y. Wimalasiri and L. Zou on the capacitive deionization (CDI) performance of a carbon nanotube/graphene (CNT/G) composite electrode. Steps such as exfoliation, CNTs separation and chemical reduction that were used to prepare the CNT/G composite reported in this study were carried out at substantially different conditions, compared to two previous reports referred by Biesheuvel et al. We find the direct comparison of our results with these two studies has been done without considering these differences and their significant implications for the resultant material properties. This letter provides our responses and clarifications to their comments. (C) 2014 Elsevier Ltd. All rights reserved.
