“…mesoAu) is (electro)catalytically more active, due to large surface areas, highly accessible inner sites and abundance of low-coordination surface atoms 11–14. To date, various nanosynthesis methodologies and techniques, including alloying–dealloying,7,15,16 electrochemical reduction,12,17,18 soft-/hard-templating,12,13,19–21 and other methods,22–24 have been used to generate mesoAu. However, the accessible morphologies were generally limited to powders with irregular shapes or films on conductive substrates.…”
