Nanocrystalline intermetallics on mesoporous carbon for direct formic acid fuel cell anodes Xiulei Ji1, Kyu Tae Lee1, Reanne Holden1, Lei Zhang2, Jiujun Zhang2, Gianluigi A. Botton3, Martin Couillard3 and Linda F. Nazar1 * Shape- and size-controlled supported metal and intermetallic nanocrystallites are of increasing interest because of their catalytic and electrocatalytic properties. In particular, intermetallics PtX (X 5 Bi, Pb, Pd, Ru) are very attractive because of their high activity as fuel-cell anode catalysts for formic acid or methanol oxidation. These are normally synthesized using high-temperature techniques, but rigorous size control is very challenging. Even low-temperature techniques typically produce nanoparticles with dimensions much greater than the optimum
