Beschreibung
Zusammenfassung:	The invention provides a method for preparing polystyrene/noble metal composite particles. The method comprises the following steps: (1) providing an aqueous dispersion of noble metal nano-particles which are not subjected to surface treatment; (2) providing a dichloromethane solution of common polystyrene; (3) mixing the aqueous dispersion of the noble metal nano-particles and the dichloromethane solution of common polystyrene, and carrying out ultrasonic treatment at 10-25 DEG C to prepare a Pickering emulsion; (4) volatilizing the emulsion at 25-50 DEG C to remove dichloromethane, centrifuging, washing and drying to obtain the polystyrene/noble metal composite particles. The preparation method is simple and quick and low in production cost, and is suitable for industrial production.
