Abstract

This communication reports a simple approach to synthesize Cu₂O@Pt nanocatalysts with different contents of platinum by using the galvanic replacement reaction. And the mass and specific activities of the Cu₂O@Pt_0.07 nanocatalyst (0.611 mA μg_Pt⁻¹, 1.68 mA cm⁻²) are 2.8 and 4.3 times higher than that of the commercial Pt/C catalyst.
