The role of anisotropic structure and its aspect ratio: high-loading carbon nanospheres supported Pt nanowires with high performance toward methanol electrooxidation

High-loading carbon supported Pt nanowire electrocatalysts are successfully synthesized in a mild one-pot template- and surfactant-free route. The high electrocatalytic activity, Pt utilization, and long-term stability toward methanol are ascribed to the anisotropic structural properties, exposure of specified planes, and the role of support on good dispersion.
