Noncloggingly Sieving Sub-6 nm Nanoparticles of Noble Metals into Conductive Mesoporous Foams with Biological Nanofibrils

Porous metal foams have been one of the most sought-after materials owing to their combination of bulk metallic characteristics (e.g., thermal/electrical conductivity and ductility) and nanometric size-effect properties (e.g., catalytic reactivity, plasmonic behavior, and high surface area). Traditional sol–gel approaches, though one of the most frequently used method to produce mesoporous metal foams, were hindered for scalable production and...
