Abstract

Abstract: Self-supported one-dimensional (1D) mesoporous Pt nanowires (NWs) are prepared by confining micelle assembly in channels of a polycarbonate (PC) membrane. The obtained mesoporous Pt NWs show very high electrochemical activity and excellent durability as catalysts for methanol oxidation reaction (MOR) in comparison with the commercially available Pt black (PtB) catalyst. This work demonstrates that an appropriate combination of both self-supported 1D shape and mesoporous architecture indeed improve the electrocatalytic performances which is critical for further implementation and practical applications.
