Dealloying, a famous ancient etching technique, was used to produce nanoporous metals decades ago. With the development of dealloying techniques and theories, various interesting dealloying products including nanoporous metals/alloys, metal oxides and composites, which exhibit excellent catalytic, optical and sensing performance, have been developed in recent years. As a result, the research on dealloying products is of great importance for developing new materials with superior physical and chemical properties. In this paper, typical dealloying products from Cu-based metallic glasses after dealloying in hydrofluoric acid and hydrochloric acid solutions are summarized. Several potential application fields of these dealloying products are discussed. A promising application of nanoporous Cu (NPC) and NPC-contained composites related to the energy storage field is introduced. It is expected that more promising dealloying products could be developed for practical energy storage applications.
脱合金化是一种著名的古代蚀刻技术，几十年前就被用于生产纳米多孔金属。随着脱合金化技术和理论的发展，近年来已开发出各种有趣的脱合金化产物，包括纳米多孔金属/合金、金属氧化物和复合材料，它们表现出优异的催化、光学和传感性能。因此，对脱合金化产物的研究对于开发具有优异物理和化学性质的新材料具有重要意义。本文总结了铜基金属玻璃在氢氟酸和盐酸溶液中脱合金化后的典型脱合金化产物。讨论了这些脱合金化产物的几个潜在应用领域。介绍了纳米多孔铜（NPC）和含NPC复合材料在储能领域的一个有前景的应用。预计可以开发出更多有前景的脱合金化产物用于实际储能应用。
