文摘

Pt nanoparticles are synthesized by plasma sputtering in water. Pt/C/TiO2 nanotubes shows better mass activity and CO-poisoning tolerance than Pt/C. TiO2 nanotubes are more suitable for support materials than TiO2 small particles. The metal-support interactions between Pt and TiO2 nanotubes are detected by XPS.
