Abstract

image

Capacitive deionization (CDI) is a competent water desalination technique offering an appropriate route to obtain clean water. On page 3917, Y.-M. Yan, K.-N. Sun and co-workers design and prepare a 3D-structured, graphene-based electrode using sponge (polyurethane, PU) as a template. The electrode possesses a large surface area, wide pore size distribution from nanopores to micropores, and low internal resistance, therefore exhibiting a remarkable electrosorptive capacity of 4.95 mg g−1 and a desorption rate of 25 min.
