Tuning Pt-skinned PtAg nanotubes in nanoscales to efficiently modify electronic structure for boosting performance of methanol electrooxidation

[Display omitted] •Pt-skinned PtAg bimetallic nanotubes with the Pt skin as thin as 1.5 nm are prepared.•The electronic structure of Pt in PtAgNTs is prominently optimized by Pt skin.•The dissociation of methanol molecules is highly enhanced by PtAgNTs.•PtAgNTs could reduce the adsorption energy of...
