On page 2091 conductive polypyrrole is integrated by Z. Liu, J. Zhai, and co‐workers into alumina nanopore arrays to construct organic/inorganic hybrid nanochannels. The protonation and deprotonation of surface groups upon pH variation contributes to the pH‐tunable ion rectification. Positive charges in polypyrrole 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.
