摘要

Organic/inorganic hybrid nanochannels are constructed by integrating conductive polypyrrole (PPy) into alumina nanopore arrays. The protonation and deprotonation of surface groups upon pH variation contribute to the pH-tunable ion rectification. Positive charges in PPy layer induced by the cooperative effect of light and protons are used to regulate the channel flux, which results in a light-responsive ion current.
