a–d Gold gels fabricated by destabilizing different-ligands-stabilized gold NPs with NaBH4, TEM images and photographs (insets). e The size of different-ligands-stabilized gold NPs and the ligament size of the corresponding gold aerogels (as derived from TEM analysis, error bars depict the standard deviation). A comparison of f the ligament size and g the ligament size vs. BET surface area of gold aerogels reported in literature, where panels a–i correspond to the references5,16,21,24,39,40,41,42,43, respectively. TEM images and photographs (insets) of h Pd, i Ru, j Rh, and k Os aerogels. STEM-EDX maps of l Au-Pd, m Au-Ag, n Au-Ru, and o Au-Ir aerogels. The scale bars are 50 nm in a–d, h–k, and are 20 nm in l–o.
