Well-defined nanostructures synthesized by optimized anodic aluminum oxide template — •Linfeng Su, Huaping Zhao, and Yong Lei — Fachgebiet Angewandte Nanophysik, Institut für Physik & IMN MacroNano, Technische Universität Ilmenau, 98693 Ilmenau, Germany

The template method has unique advantages in the design and synthesis of materials with specific nanostructures but with some disadvantages. In recent years, through in-depth research and improvement of its preparation methods, the five shortcomings of the traditional anodic aluminum oxide (AAO) template method, such as short-range order and long-range disorder, insulator, single-set of pores, large dead volume, and limited capability to tune pore shape and arrangement, have been successfully addressed by our group. Large-scale control of the shape, size, spatial configuration, and combination of in-plane and out-of-plane pores of well-defined nanostructures can be achieved, thereby broadening the diversity of nanostructures[1, 2]. In addition, we have improved the mechanical strength of the prepared AAO template, so that it can maintain the stability of the nanostructure under a pressure of 10 MPa[3]. The optimized AAO template method provides practical guidance for the design and preparation of catalysts under complex application conditions. [1] Nat. Commun., 2022, 13(1), 2435; [2] Nat.
