A simple synthesis of urchin-like Pt–Ni bimetallic nanostructures as enhanced electrocatalysts for the oxygen reduction reaction†
Abstract
The synthesis of urchin-like Pt–Ni bimetallic nanostructures is achieved by a controlled one-pot synthesis. Pt–Ni nanostructures have superior oxygen reduction reaction activities in both with and without specific anion adsorption electrolytes due to the geometric and alloying effects.
