(460c) 3D Carbon Material and Its Excellent Capacitive Deionization Performance

Capacitive deionization (CDI) as a promising technology for efficient ion removal from brackish water has attracted wide attention. Ion removal mechanism of CDI is based on electric double layer formation on electrode materials at low power supply. We constructed 3D carbon materials with large accessible surface areas and high electrical conductivity which can effectively improve the electrosorption capacity. The excellent capacitive deionization performance, which is better than commercial CDI materials (activated carbon) can attribute to the particular structure of 3D porous frameworks, proper micro/meso/macropore ratio and high electrical conductivity. Thus, 3D carbon materials have great potential for water treatment in industrial application.
