The transport behavior of solvated ions in nanopores of a zeolite Y is field responsive. As an external electric field is applied, the observed change in effective solid-liquid interfacial tension is contradictory to the prediction of classic electrochemistry theory; it considerably increases no matter whether the applied voltage is positive or negative. This may be attributed to the breakdown of solvated ion and double-layer structures in the nanoenvironment. © 2009 American Institute of Physics.
