• Gold@polydopamine particles with multi-compartment structure were synthesized by using block copolymer of PS-b-P2VP as soft template and characterized by 3D electron tomography technique.

• The particles can be applied as catalytic nanoreactors for the full kinetic study of reduction reaction of 4-nitrophenol by NaBH₄.

• The nanoreactors show remarkable enhancement of the catalytic activity under NIR irradiation.
