摘要

Artificial heterogeneous nanochannels with lightresponsive ion transport properties are demonstrated by Z. Liu, J. Zhai, and co-workers on page 424. Their fabrication includes coating an anatase TiO2 porous layer onto an alumina porous supporter, followed by chemical modification with octadecyltrimethoxysilane (OTS) molecules. The decomposition of OTS molecules by TiO2photocatalysis under UV light contributes to a change of surface wettability and an asymmetric distribution of surface negative charges, which realize the ion gating and regulatable ion rectification characteristics simultaneously.
