Nanomotors: A simplified cost-effective template approach for preparing efficient gold-free bimetal Ag–Pt nanowire motors, where the silver segment is obtained by a partial removal of the silver sacrificial layer is described (see figure). The unusual behavior, reflecting the ‘active’ role of the Ag segment and the asymmetry of the catalytic surface provides the ultrafast motion of these nanomotors.
