Nanoporous Metals Based on Metallic Glasses: Synthesis, Structure and Functional Applications

Nanoporous metals have emerged as a new class of functional materials with unique structures and properties. Compared to conventional metals and alloys, nanoporous metals possess a high surface area, unique pore size distribution and enhanced catalytic activity, making them highly desirable for a wide range of applications, such as photonics, sensing, supercapacitors and catalysis. In this review paper, we aim to summarize recent advances in the fabrication, structural regulation and functional applications of nanoporous metals and their composites via the dealloying of metallic glasses. Particularly, we will discuss the factors that affect the nanoporous structure, including precursor composition, dealloying conditions and post-treatment methods. We will also cover topics such as the preparation of immiscible nanoporous metals and the control of hierarchical nanoporous structures. Finally, we will provide a brief overview of the current situation and discuss the current challenges and potential research directions in the field.
