Abstract
This study shows the good performance of quasicrystal Al 62,2 Cu 25,3 Fe 12,5 as catalyst in catalytic reactions. This metallic catalyst without being leached with acid or base, with dry stoichiometric composition Al 62,2 Cu 25,3 Fe 12,5 revealed among the reactions occurring be a partial oxidation; formation of products which were methanol, methanol + methanoic acid, water and dimethyl ether. For this research used experimental techniques as X-ray Diffraction-XRD to follow the evolution of the alloy phase, the Scanning Electron Microscopy-SEM that allows the study of surface microstructure, (SBET) verify surface area of the catalyst quasicrystal and Transmission Electron Microscopy-TEM, studying the morphology of internal phases, quasicrystalline nuclei and defects; testing for the catalytic conversion of methanol and selectivity and products formed from this material used as catalyst. It should say, the processes of formation of the alloy depends quasicrystalline of chemical elements that compose it and the production techniques of the alloys, this may get different morphologies and different quasicrystal desired phases, can increase / decrease the icosaedral. The phase activity and stability of quasicrystal catalyst for steam reforming of methanol showed su ffi cient performance compared to other catalysts. The Fe and Cu species highly dispersed in the homogeneous layer quasicrystal catalyst increases the catalytic activity and suppresses the aggregation of Cu particles. We propose that the quasicrystal can be a good catalyst to be used in catalytic steam reforming, with high catalytic activity and excellent thermal stability.
