Maghemite particles were synthesized using a combination of combustion method and sonochemical step for preparation of Pt and Pd supported catalysts. The most active catalysts were Pd/maghemite and bimetallic Pd-Pt/maghemite, which were easily separable post-reaction due to their magnetic properties. These catalysts were immediately ready for use in 2,4-dinitrotoluene hydrogenation to produce 2,4-toluenediamine.
Maghemite particles were synthesized by using a combined combustion method and sonochemical step. Maghemite was used as carrier to prepare supported Pt and Pd catalysts after deposition via a sonochemical step. The catalysts were immediately ready to be used (metals were catalytically active) for the 2,4-dinitrotoluene hydrogenation to produce 2,4-toluenediamine. The most active catalysts were the Pd/maghemite and bimetallic Pd-Pt/maghemite. The catalysts were easily separable after reaction due to their magnetic properties.
