A Cu 2 O nanowire template is converted into a cobalt oxide nanotube heterostructure, composed of ultrathin CoO x nanosheets perpendicularly grown on the surface. As discussed by W.‐B. Cai, G. Zheng, and co‐workers in article number 1500003, this 2D/1D heterostructure allows structural optimization over different length scales for superior electrocatalytic oxygen evolution reaction activity. Electric current and oxygen bubbles are displayed from the 2D/1D cobalt oxide heterostructure surface.
