通过在聚碳酸酯（PC）膜的孔道中限制胶束组装，制备了自支撑的一维（1D）介孔Pt纳米线（NWs）。与市售的Pt黑（PtB）催化剂相比，所获得的介孔Pt纳米线作为甲醇氧化反应（莫尔）催化剂显示出非常高的电化学活性和优异的耐久性。这项工作表明，自支撑的一维形状和介孔结构的适当组合确实提高了电催化性能，这对于进一步实施和实际应用至关重要。(C)2015爱思唯尔有限公司版权所有。
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.
