Abstract

This study focuses on the structural stability of nanoporous Au foams fabricated by chemical dealloying. Thermal annealing and catalytic transformations are shown to activate coarsening processes exhibiting same overall kinetics and comparable rate. Data support the hypothesis of a mechanistic scenario dominated by surface diffusion and suggest for catalytic runs local temperatures higher than nominal ones.
