中文摘要	we reported an effective and environmentally friendly method of decorating pt nanoflowers (pt nfs) on the surface of carbon nanotubes (cnts). by reduction of k2ptcl4 with l-ascorbic acid in an aqueous solution, pt nanoparticles with a flower-like morphology were deposited onto the surface of poly(sodium 4-styrenesulfonate) wrapped cnts (pss-cnts). pss plays a dual role: dispersing stable cnts into solution in water, and providing functional groups that bind metal ions and metal nanoparticles. as-prepared pt nfs/pss-cnts showed a large electroactive specific surface area, and presented excellent electrocatalytic activity for oxygen reduction. au and pd nanoparticles could also be deposited on pss-cnts. this method could be extended to the synthesis of different kinds of metal nanoparticles on other polymer wrapped cnts. as-prepared metal nanoparticle/cnt nanocomposites could find use as electrocatalysts in polymer electrolyte membrane fuel cells.
