Ultrasmall nanoclusters are emerging nanocatalysts due to their distinct physico‐chemical properties. However, the instability and agglomeration of these nanoclusters restrict their practical application. Herein, we designed a negatively charged cross‐linked polystyrene (PS) microsphere as support and decorated it with positively charged ultrasmall [Au4Cu5(Dppm)2(C6H11S)6]+[BPh4]−(Au4Cu5, in which Dppm stands for bis‐(diphenylphosphino)methane) nanoclusters through strong electrostatic adsorption, as evidenced by X‐ray photoelectron spectroscopy. The PS@Au4Cu5nanocomposites were well‐dispersed in water, exhibiting enhanced catalytic activity for the reduction reaction of 4‐nitrophenol to produce 4‐aminophenol. These findings open promising opportunities for supported nanocluster catalysis.
