摘要：New iron silicides based hydrogenation catalysts have been prepared by organometallic chemical vapor deposition of Fe(CO)(4)(SiCl(3))(2) precursor on silica support. Fe(CO) 4(SiCl(3))(2) was synthesized from Fe(3)(CO)(12) and SiHCl(3) at 120 degrees C, as confirmed by FTIR, (13)C and (29)Si NMR. The FeSi loadings have been varied by changing the amount of the precursor. XRD patterns only showed a diffraction peak due to silica, indicating that iron silicide particles were too small to be detected. TEM image showed that the lattice spacing of the particles was 0.2578 nm, which matched well with the lattice spacing 0.2591 nm of the FeSi (111) plane. TEM image showed that the size of iron silicide particles dispersed on the silica was about 3 nm. However, the so-prepared FeSi/SiO(2) catalysts showed little catalytic activity in naphthalene hydrogenation. More studies would be needed to have a better understanding on how to improve the efficiency of these new catalysts.
