Synthesis of Out‐of‐Substrate Au–Ag Nanoplates with Enhanced Stability for Catalysis

Abstract

Gold plated: Gold–silver alloy nanoplates (see image) with out-of-substrate orientation are synthesized on large-area supports by growth of silver nanoplates on gallium arsenide wafers followed by an overgrowth and alloying process. The surfaces of the nanoplates are highly exposed to the surrounding environment, thus increasing their catalytic efficiency.
