Abstract

High-stability Pt electrocatalysts have been prepared using hierarchical CNT@TiO₂ structures composed of TiO₂ nanosheets grafted on the CNT backbone as the support. The as-prepared Pt/CNT@TiO₂ electrocatalysts manifest high electrocatalytic activity with greatly improved stability compared to conventional CNT or carbon black supported Pt electrocatalysts.
