Well-defined nanostructures for energy storage and conversion applications — •Ningxiang Wu, Huaping Zhao, and Yong Lei — Fachgebiet Angewandte Nanophysik, Institut für Physik & IMN MacroNano, Technische Universität Ilmenau, 98693 Ilmenau, Germany

Template-based technique provides a perfect approach to realize well-defined arrayed nanostructures within large-scale.[1]We have developed nanostructuring techniques mainly using anodic aluminum oxide templates with scalable, parallel and fast processes for fabricating different three-dimensional and surface nanostructures.[2]The obtained well-defined nanostructures possess large-scale arrayed configuration, high structural density, perfect regularity and cost-effectiveness, and are highly desirable for constructing different nano-devices especially for energy storage and conversion applications, including rechargeable sodium-ion and potassium-ion batteries, supercapacitors, and photo electrochemical devices.[3-4]The device performances demonstrated that the obtained nanostructures benefit these applications through the precise control over the structural features enabled by the geometrical characteristics of the templates. These achievements indicate the high potential and importance of template-based nanostructuring techniques for both basic research and device applications.[1] Nat.Commun.,2022,13,2435, [2] Nat.Nanotechnol.,2017,12,244, [3] Nat.Commun.,2018,9,1720, [4] Nat.Commun.,2016,7,10348
