The Pt tube-in-tube arrays (TTAs) were designed and synthesized by ZnO template-assisted electrodeposition. As a robust integrated 3D electrocatalyst with high utilization rate and fast transport of electroactive species, the Pt TTAs exhibit a high electrochemically active surface area (ECSA) of 64.9 m2/gPt. Compared with Pt NTAs and commercial Pt/C catalyst, the Pt TTAs exhibit much improved electrocatalytic activity and durability for methanol oxidation. In addition, the Pt TTAs as electrocatalysts exhibit superior CO poisoning tolerance. This work shows the significant progress of Pt-based electrocatalysts with high-performance for direct methanol fuel cells.
