现代社会的快速发展对能源的高效转换和储存提出了越来越高的要求。电化学装置是最终替代化石燃料的最可行的选择，但存在耐久性、可操作性等问题。非均质纳米结构阵列以其独特的优势引起了人们的广泛关注，并产生了良好的电化学性能。为了深入了解它们的工作模式，本文将重点研究每个单元中不同成分之间的相互联系，以将微观电化学过程与宏观性能联系起来。本文首先总结了采用非均质纳米结构阵列的动机。然后，综合分析了“功能-功能”、“功能-辅助”、“单机装置”三种工作模式的设计原理，阐明了电化学能量转换和存储过程中不同成分之间的相互联系。太阳能水分解（能量转换）、碱离子电池和超级电容器（能量存储）被统称为典型的电化学能源技术，以说明非均质纳米结构阵列的优势。最后，对相关领域的展望进行了总结，以拓宽非均质纳米结构阵列的发展前景。
Rapid development of modern society raises more and more requirements for highly efficient energy conversion and storage. Electrochemical devices stand out as a most viable option for eventual substitute for fossil fuels, but suffer from problems like durability, operability, etc. Heterogeneous nanostructure arrays with distinguished superiorities have thus attracted intensive attention and yielded favorable electrochemical performance. In pursuit of deep understandings of their working modes, this review will focus on the interconnection among different constituents within each individual unit to correlate microscopic electrochemical processes with macroscopic performance. Here, the motivation of employing heterogeneous nanostructure arrays is first summarized. Then, the design principles, including three working modes, ‘Function-Function’, ‘Function-Assistance’, ‘Single-unit device’, are analyzed comprehensively to illuminate the interconnection among different constituents in electrochemical energy conversion and storage processes. Solar water splitting (energy conversion), alkali-ion battery and supercapacitors (energy storage) are termed collectively as typical electrochemical energy technologies to illustrate the superiorities of heterogeneous nanostructure arrays. Finally, perspectives of related fields will be concluded to broaden the future of heterogeneous nanostructure arrays.
