Abstract
This study explores the interplay between mechanics, microstructural geometry, and hy drogen interaction in nanoporous (np) materials, focusing on np Nb and np Pd, with np Au as a benchmark. First, a novel scaling law for Young’s modulus is established, incorporating the network’s topological connectivity. Based on that, experimental studies on np Nb further reveal that structural dispersion must be acknowledged when comparing dealloying methods of
np materials. The second part examines the hydrogen sorption kinetics of np Pd, emphasizing the role of ligament size. Findings suggest that interfacial injection controls the sorption rate, leading to the development of a new kinetic rate law.
