One‐Pot Synthesis of Highly Anisotropic Five‐Fold‐Twinned PtCu Nanoframes Used as a Bifunctional Electrocatalyst for Oxygen Reduction and Methanol Oxidation

Key Points

• To synthesize highly anisotropic five-fold-twinned PtCu nanoframes with protruding nanothorns via a one-pot method and evaluate their bifunctional electrocatalytic activity.
• Synthesized five-fold-twinned PtCu nanoframes with nanothorns protruding from their edges using a facile one-pot synthesis.
• Evaluated electrocatalytic performance for both the oxygen reduction reaction and the methanol oxidation reaction under alkaline conditions in comparison to commercial Pt/C catalysts.
• Successfully fabricated highly anisotropic PtCu nanoframes with distinct edge nanothorns using one-pot chemistry.
• Achieved enhanced electrocatalytic activity for both oxygen reduction and methanol oxidation in alkaline media relative to commercial Pt/C.
