摘要: Palladium nanoparticles have been successfully incorporated into a porous diblock copolymer template using novel technique. An ordered bicontinuous double gyroid phase was created from poly(isoprene)-block-poly(2-vinylpyridine). The poly(isoprene) matrix of this structure subsequently removed by ozonolysis, creating high specific surface area material composed poly(2-vinylpyridine) network texture. ions were then adsorbed and reduced within the material. Large loadings possible. It also possible to kinetically control dimensions (∼5−10 nm) number density nanoparticles. Because porosity template, technique is very promising for high-performance catalysts other applications.
