Sašo Gyergyek, Darko Makovec from the Department for Materials Synthesis and Andraž Kocjan from the Department of Nanostructured Materials of the Jožef Stefan Institute, in collaboration with researchers from the Department of Catalysis and Reaction Engineering of the National Institute of Chemistry, published an article “Hierarchical Ru-Bearing Alumina/Magnetic Iron-Oxide Composite for the Magnetically Heated Hydrogenation of Furfural“ in the scientific journal Green Chemistry. The paper demonstrates the application of magnetic heating of nanoparticles in AC-field to drive the chemical reaction. The authors showed that the conversion of furfural to furfuryl alcohol over the catalyst in the same time interval reached 95% when “targeted” heating by AC magnetic field was used, but only 63% when conventional heating was applied. They were the first to show that a well-designed hierarchical composite can simultaneously serve as a catalyst and heat source to drive a technologically important chemical reaction in a slurry-type reactor.
