Title: Anodic Electrocatalyst Synthesis for Fuel-Cell Direct Methanol Application Abstract : Iran's capacity for production of methanol is huge. Thus, direct utilization of methanol in fuel cell seems to have a promising prospect. Anodic electrocatalyst is needed for conversion of methanol into hydrogen and its utilization in fuel cells. Studies show that catalysts with nano-tube base are the best choices. Some metallic particles are precipitated on nano-tubes for production of catalysts. Platinum is considered as the best single metal catalyst for methanol oxidation. But due to poisoning effect of Pt catalysts in methanol fuel cells as a result of production of CO, it’s important to use binary and ternary metallic catalysts. Some metallic compounds composed of Pt, Ru and Ni are suggested for this coat. The present study on synthesis of anodic electrocatalyst according to a precipitation/reduction method assisted by ethylene glycol (EG). Platinum/carbon-nanotube, platinum- ruthenium/carbon-nanotube and platinum-ruthenium-nickel/carbon-nanotube were first produced and then characterized by scanning electron microscopy and x-ray diffraction analysis. Carbon-nanotubes were prepared by oxidization in hot sulfuric and phosphoric acid (2M H2SO4 and 8M HNO3 at 100ºC) and then precipitation of metallic particles was achieved by chemical reduction of H2PtCl6.6H2O, RuCl3, and NiCl2.6H2O precursors in EG. For modification of condition and preparation of complicated salts and ions, NaHSO3 was added to the solution. After optimization of the method, the best condition for homogenous precipitation was obtained. |
