Abstract

The Fe 2 (MoO 4 ) 3 /MoO 3 nanocatalysts comprising Fe 2 (MoO 4 ) 3 nanoparticles supported on MoO 3 nanorods were synthesized via two-step solution combustion approach and their catalytic performance for the selective oxidation of methanol were evaluated. The materials have been characterised using electron microscopy, powder X-ray diffraction and Raman spectroscopy. First, MoO 3 nanoparticles were prepared by solution combustion reaction employing ammonium nitrate as oxidant, and ammonium molybdate as fuel and Mo source. The synthesized MoO 3 nanoparticles were found to have orthorhombic crystal structure and rod-like shape with width and thickness of 50-200 nm and length of 0.2-1 μm. Then, the MoO 3 nanorods were dispersed in aqueous solution of the ferric nitrate as oxidant and glycine as fuel, and combustion was performed to prepare MoFeO x /MoO 3 precursor particles. To investigate the formation process of Fe 2 (MoO 4 ) 3 phases on MoO 3 nanorods, the precursors were calcined at different temperatures of 300-500 °C for 2h. The Fe 2 (MoO 4 ) 3 phases were not formed on MoO 3 nanorods in samples calcined at 300 and 400 °C. The XRD patterns of the samples calcined at 300 and 400 °C were consistent with that of the uncalcined sample. The Fe 2 (MoO 4 ) 3 /MoO 3 nanocatalysts comprising Fe 2 (MoO 4 ) 3 nanoparticles supported on MoO 3 nanorods were synthesized when the precursor particles were calcined at 500 °C for 2h. The size of Fe 2 (MoO 4 ) 3 phases formed on MoO 3 nanorods was less than 40nm. The catalytic performance of the synthesized Fe 2 (MoO 4 ) 3 /MoO 3 nanocatalysts for the selective oxidation of methanol to formaldehyde were compared with commercial catalysts. Selectivity to formaldehyde of the synthesized Fe 2 (MoO 4 ) 3 /MoO 3 nanocatalyst was higher than that of the commercial catalyst.
