Abstract
observation of the dynamic evolution of the Au NP morphology is important in understanding the structural transformation of Au NP catalysts at the nanometer scale and determining the active site motifs under the reaction conditions. Moreover, this would allow us to further understand the size effect and the dynamic evolution behavior of the active center of Au NP catalysts, thereby providing a new idea for the development and application of new catalysts and strong theoretical support for heterogeneous catalytic reaction mechanisms.
