This study focuses on the effects of catalytic activity on nanoporous Au catalysts fabricated by dealloying. Nanoporous Au structures are shown to coarsen with similar kinetics over a broad temperature range. A variation in the apparent activation energy suggests that coarsening is controlled by different rate-limiting steps at high and low temperatures.

Abstract

This study focuses on the effects of catalytic activity on nanoporous Au catalysts fabricated by dealloying. Nanoporous Au structures are shown to coarsen with similar kinetics over a broad temperature range. A variation in the apparent activation energy suggests that coarsening is controlled by different rate-limiting steps at high and low temperatures.
