- •
The Pt-Co NS@carbon sponge electrode shows unique nanosheet structure on the three-dimensional (3D) porous network skeleton with a large surface area.
- •
The Pt-Co NS@carbon sponge electrode achieves a reduction current density of −1.38 A cm−2 mg−1 in 3.0 mol L−1 KOH and 1.5 mol L−1 H2O2 at −0.50 V (vs. Ag/AgCl)
- •
The Pt-Co NS@carbon sponge electrode exhibits a desirable stability for the H2O2 electroreduction.
