摘要：
Well-defined surfactant-stabilized "Co-shell Au-core" bimetallic nanoparticles were successfully prepared in the presence of the mixture of two surfactant molecules. The formation of these core-shell structures is driven by the thermal deposition of Co(CO)(g) by refluxing p-xylene solution in the presence of the pre-formed gold nanoparticles which were prepared by NaBH4-reduction of RAuCl4. Continuous layer of cobalt without vacancies wrapping the gold core was revealed by TEM observation and the obtained bimetallic nanoparticles could be dispersed stably.
