Abstract
With the exponentially growth of world population and the fast industrial development, the demand for clean and accessible fresh water increased dramatically and is expected to grow continually. Capacitive deionisation (CDI) technology is a novel low energy-consuming, low-cost and green desalination approach, therefore, has attracted numerous attentions and is regarded as a promising water purification technology for the future. This thesis aims to find cost-effective and high performance electrode materials for the CDI process, therefore, nanostructure porous carbons, carbon nanotubes (CNTs) and its composites, such as manganese oxide (MnO2)/porous carbons and functionalised CNTs were synthesised, and applied in the CDI process. Nanoporous carbons and CNTs are promising electrode materials because of their high surface area, excellent electrochemical properties, suitable pore arrangement, mesoporosity, and suitable electrical conductivity. In the MnO2/carbon composites, MnO2 contributed to the additional adsorption and insertion of cations, thus enhanced the CDI performance. On the other hand, CNTs functionalised by ion-selective groups showed advanced CDI behaviours owing to that the co-ion effects are minimised by surface charged groups.
