纳米多孔金(np-Au)具有有趣的材料特性,由于其高比表面积,良好表征的硫醇-金表面化学,高电导率和降低的刚度,为许多应用提供了潜在的好处。对np-Au的研究已经在各个方面进行,包括先进的微加工和表征技术,以探测从燃料电池到电化学传感器的不寻常的纳米级特性和应用。在这里,我们提供了一个审查的最新进展,在np-Au的研究,特别强调微细加工和表征技术。最后,我们简要概述了纳米多孔金属研究中需要克服的挑战。
Nanoporous gold (np-Au) has intriguing material properties that offer potential benefits for many applications due to its high specific surface area, well-characterized thiol-gold surface chemistry, high electrical conductivity, and reduced stiffness. The research on np-Au has taken place on various fronts, including advanced microfabrication and characterization techniques to probe unusual nanoscale properties and applications spanning from fuel cells to electrochemical sensors. Here, we provide a review of the recent advances in np-Au research, with special emphasis on microfabrication and characterization techniques. We conclude the paper with a brief outline of challenges to overcome in the study of nanoporous metals.
