N2 - Ordered mesoporous thin film carbon (TFC) material, of short channels vertical to the film, was synthesized by the replication of mesoporous silica SBA-15(⊥) template and was deposited with PtRu nanocatalyst as an anodic material in direct methanol fuel cell (DMFC). The anode nanocatalyst PtRu was characterized by XRD, Raman, XPS, nitrogen adsorption, and COad stripping. Electrocatalytic activity, characterized by anodic current, was compared with PtRu supported on various carbon supports, including TFC, CMK-3, and XC-72. The much enhanced methanol electrochemical oxidation activity in PtRu/TFC was ascribed to increased nanocatalysts' utilization efficiency with the short nanochannels of TFC.
