“…Supported gold NPs have shown promising catalytic performance for a variety of reactions, including propene oxidation [2], the water gas shift reaction [3], selective oxidation of alcohols [4], and selective hydrogenation of unsaturated aldehydes [5,6], among others [7]. The performance of gold NPs is highly dependent on the particle size, the nature of the support, and the preparation procedure, and the effects of these factors can be understood based on different active site models, such as low-coordinated gold atoms [8,9], the perimeter interface between gold and the support [10][11][12], and charged gold species [13][14][15].…”
