Synthesis of Pt–Ru Nanoporous Fibers by the Nanoscale Casting Process Using Supercritical CO2 for Electrocatalytic Applications

The Pt–Ru nanoporous fibers prepared by the nanoscale casting process using supercritical fluids (NC-SCF), templating process using SCFs, retained the structure with the high surface area and fibrous shape of the activated carbon template and exhibited a high activity as the anode catalyst for direct methanol fuel cells.
