Abstract

Electrochemical oxidation of aluminium in acidic electrolyte solutions, also known as anodizing, is a widely used process for the finishing of pure aluminium and its alloys. The resulting anodic aluminium oxide (AAO) porous films play a significant role in modern science and technology. One of the most exciting features of AAO is the self-organization of pores into two-dimensional hexagonal patterns under specific anodizing conditions. The combination of a hexagonal arrangement of pores and precise control over pore diameter, interpore distance, and film thickness gives rise to a wide range of potential applications from decorative coatings to quantum technologies. This review discusses the kinetic approach to the guided search for anodizing conditions that lead to the formation of highly ordered porous structures, as well as recent data on how the crystallographic orientation of the aluminium substrate affects the growth rate and structure of AAO.

铝在酸性电解质溶液中的电化学氧化，也称为阳极氧化，是一种广泛用于纯铝及其合金表面处理的工艺。阳极氧化铝（AAO）多孔薄膜在现代科学技术中发挥着重要作用。AAO 最令人兴奋的特点之一是，在特定的阳极氧化条件下，孔隙可自组织成二维六边形图案。孔隙的六边形排列与对孔隙直径、孔隙间距和薄膜厚度的精确控制相结合，产生了从装饰涂层到量子技术等广泛的潜在应用。这篇综述讨论了引导寻找可形成高度有序多孔结构的阳极氧化条件的动力学方法，以及有关铝基底的晶体学取向如何影响 AAO 生长速度和结构的最新数据。

期刊介绍： The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry. The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces. The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis. The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
