Nanostructured Molybdenum Carbide:  Sonochemical Synthesis and Catalytic Properties

Development of Plasma-Sprayed Molybdenum Carbide-Based Anode Layers with Various Metal Oxides for SOFC

“…It was demonstrated that at elevated pressure, the choice of the support for the Mo 2 C dry reforming catalyst is crucial to catalyst stability, and the order of catalyst stability was found to be in this order (Mo 2 C-Al 2 O 3 > Mo 2 C-ZrO 2 > Mo 2 C-SiO 2 > Mo 2 C-TiO 2 ). Mo 2 C also is an excellent dehydrogenation catalyst [12] with activity comparable to that of Pt [13]. Considering these key factors, composite powder materials (Mo 2 C-ZrO 2 ) can potentially be used for an improved anode performance in direct hydrocarbon SOFCs.…”

Sonochemistry under an Applied Magnetic Field: Determining the Shape of a Magnetic Particle

“…1,2 This work has led to an extensive investigation of the decarbonylation reaction. Following Suslick's method, alloys, [3][4][5][6] carbides, 7 nitrides, 8 oxides, 9,10 and various ferrites 11 have also been prepared. In all cases, the products are obtained in the amorphous form, with the particles of nanometer size.…”

Effects of Ultrasound and Microwaves on Selective Reduction: Catalyst Preparation and Reactions

“…[21,50] Meanwhile, strong shock waves and micro-jets, that can move at over 400 km/h, that are created by cavitation bubble implosion can crush catalyst particles and suppress agglomeration, resulting in finer and more dispersed catalyst particles. [51] The sonochemical decomposition of volatile organometallic compounds produces high surface area solids that consist of nanometer cluster agglomerates, [52] such as nanosize MoC, MoS2, or Fe [53][54][55][56] or noble metal catalysts. [57,58] Sonication was also found to be efficient in the preparation of supported Ru and Pd samples as well.…”
