“…The first comment made by Biesheuvel et al [1] relates to the high capacitive deionization performance of the CNT/ graphene (CNT/G) composite (26.42 mg/g) reported by Wimalasiri and Zou (WZ) [2]. In response, we confirm that the reported electrosorption capacity was the result of duplicate experiments of CDI with separate batches of materials.…”

“…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.Ó 2014 Elsevier Ltd.

“…The elements of Fe and N arise from the carbon source of iron phthalocyanine (FeC 32 N 8 H 16 ). And, a sharp peak for C1s at 284.8 eV is observed to evaluate the binding behavior of the elements in the CNTs-G composite, which is ascribed to the graphitic carbon [17,18].…”

One of the most promising applications of carbon nanotubes (CNTs) is the emission electronics, in which CNTs are used as a field emission electron source. Lots of electronic devices are based on electron sources, which are the most important components served as state-of-art nanoelectronics devices in nowadays, such as field emission displays, miniature mass spectrometers, scanning ultrafast electron microscopes, X-ray generators, free electron lasers, THz sources, and so on. Field electron emission is based on the physical phenomenon of quantum tunneling, in which electrons are emitted from the surface of materials into vacuum on the condition of applied voltage. CNTs have many advantages as field emitters comparing with conventional metallic emitters like familiar examples of tungsten, gold, copper, and molybdenum. Electron emission from cold cathodes of CNTs has attracted attentions of numerous scientists, and substantial researches have been conducted on their properties and applications. In this chapter, we will focus on the field emission of CNT cold cathodes as an electron source, including of how to synthesize it by chemical vapor deposition (CVD) method and how to realize its electron emission. In addition, we will report pulsed electron emission of CNT cathodes. The combination of the laser pulse and the cold cathode will offer the possibility of pulsed field emission. Our approach demonstrates the growth mechanism and the emission mechanism of CNTs, which is beneficial for controlling the performance of its fascinating application on emerging fields.

“…In a CDI transport of ion is due to electrostatic adsorption, not due to oxidation and reduction reactions [7]. CDI has benefits of being eco-friendly, having less energy consumption and working costs than other desalination technologies, simplicity in regeneration and maintenance compared with other conventional techniques of desalination [8,9]. In capacitive deionization techniques one or several pairs of oppositely charge electrodes are used as a capacitor for deionization of water.…”

Abstract:A mini review of a recently developing water purification technology capacitive deionization (CDI) applied for removal of pollutant ions is provided. The current progress of CDI for removal of different pollutant ions such as arsenic, fluoride, boron, phosphate, lithium, copper, cadmium, ferric, and nitrate ions is presented. This paper aims at motivating new research opportunities in capacitive deionization technology for removal of pollutant ions from polluted water.
