We report a mesoporous carbon based membrane that can be used as on/off switch to control the transport of organic molecular species and metal ions across it using an electrochemical potential. In absence of an electrochemical potential, both cationic and anionic molecules are freely transported across the membrane by concentration gradient (diffusion). However, when an electrochemical potential is applied across the membrane, the transport of ions across the membrane is inhibited. This is attributed to the formation of an electric double layer inside the pores of carbon membrane that prevent passage of ions through it.
