| Abstract: | The micelles was firstly prepared by self-assembled poly(styrene)-block-poly(4-vinylpyridine)(PS-b-P4VP) in selective solution of ethylbenzene.The Cu2+ was inserted into the micelles core by complex of P4VP and Cu2+.Copper nanopartices were subsequently obtained by loading Cu nanoparticle onto micelles catalyst system through site reduction.The size of Cu nanoparticles in the micelle core is 2~3 nm by transmission electron microscope.Micelles-copper nanoparticles were applied in the catalytic oxidation of e... |
