▎ 摘  要

Biology systems harvest solar energy to regulate ions and molecules precisely across cell membrane that is essential to maintain their life sustainability. Recently, artificial light-driven directional ion transport through graphene oxide membranes has been established, where the membrane converts light power into a transmembrane motive force. Herein, we report a silver nanoparticles decorated graphene oxide membranes for enhanced photo-driven ionic transport. Asymmetric light stimulated charge carrier dynamics, such as advanced light absorption efficiency, extended lifetime and efficient separation of photo-excited charge carriers, are account for the ion-driven force enhancement. Based on metal nanoparticles decoration, the concept of the guest-interactions of plasmon-enhanced photo-driven ion transport in two-dimentional layered membranes will stimulate broad researches in sensing, energy storage and conversion and water treatment.
