One-pot synthesis of cubic PtPdCu nanocages with enhanced electrocatalytic activity for reduction of H2O2

Cubic PtPdCu nanocages were prepared using Cu₂O as sacrificial templates and applied to detect H₂O₂. PtPdCu nanocages exhibit high sensitivity at a low potential of 0.05 V. The high activity is related to the hollow structure and synergistic effect.
