Diphosphine-induced morphological modification in Au nanoclusters and its implications for catalytic activity regulation

Abstract

Diphosphine-induced structural transformation was performed to modify the local structure of Au₄₄, leading to the formation of an Au₄₀ nanocluster. The regular box-like morphology of Au₄₄ is converted into a sharp shape for Au₄₀. This change in morphology results in the activity enhancement of Au₄₀ in the photocatalytic degradation of rhodamine B.
