In article 1500761, Bao Zhi Yu and co‐workers describe the synthesis of innovative hierarchical α‐MnO 2 tube‐on‐tube arrays (HMNTAs) with superior pseoducapacitor performance. The branch nanotubes are subtly and precisely assembled onto the backbone nanotube via {110} interfacial coherent growth, showing a unique edge‐to‐edge structure. Owing to remarkable structural features, the HMNTAs demonstrate increased specific area, shortened the diffusion and transport distance, and strong aggregation‐resistance. This work brings new thoughts for designing novel hierarchical nanoarrays for various structure‐sensitive applications.
