Abstract

Abstract : The Cover Feature shows the spontaneous galvanic deposition of metallic Pt nanoparticles on the top, but also inner TiO2 nanotube surfaces. High‐aspect‐ratio and heavily reduced TiO2 serves as the sacrificial template during this electroless deposition. A high‐performing and stable hydrogen evolution cathode in acidic media is demonstrated and prepared via minimal engineering and low noble metal loadings.
