- Abstract
- Structure-controlled Pt-based catalysts have been known to exhibit improved electrocatalytic activities due to particularly modulated surface structures favorable for alcohol electrooxidation. We report Pt-Ni alloy dendrite structure for formic acid electrooxidation prepared by a thermal decomposition method. The Pt-Ni nanodendrites display 3-dimentional nanostructure and homogeneous alloy formation between Pt and Ni. In formic acid electrooxidation, the Pt-Ni alloy nanodendrite catalyst exhibits much improved electrocatalytic activity.
