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.

燃烧法结合声化学步骤合成磁赤铁矿负载的2,4-二硝基甲苯加氢催化剂

磁赤铁矿颗粒是通过使用组合燃烧法和声化学步骤合成的。在通过声化学步骤沉积后，磁赤铁矿被用作载体以制备负载的 Pt 和 Pd 催化剂。该催化剂可立即用于 2,4-二硝基甲苯加氢以生产 2,4-甲苯二胺（金属具有催化活性）。最活跃的催化剂是 Pd/磁赤铁矿和双金属 Pd-Pt/磁赤铁矿。由于其磁性，催化剂在反应后很容易分离。
