Amphiphilic block copolymer-stabilized PtRu nanoparticles highly dispersed on multi-walled carbon nanotube for methanol oxidation

► An efficient method is presented for modify MWCNTs with PtRu nanoparticles. ► Synthesis of PtRu nanoparticles using P123 is a very mild method. ► This is a development for synthesis method of fuel cell catalyst.
