1D SiC decoration of SiC macroscopic shapes for filtration devices

Résumé

The synthesis of a hierarchical support, constituted of a network of SiC nanofibers deposited on a SiC foam host resulting in a ceramic material with a controlled macroscopic shape and associated high specific surface area superior to 50 m2 g1, has been reported for the first time. The new composite combines the nanoscopic properties of the SiC nanofibers’ network and controlled macroscopic shape and open porosity, typical of a SiC foam structure. The introduction of the nanostructures onto the host material allows a dramatic increase in the effective surface area which is extremely useful for the chosen field of application. This new type of material has been efficiently employed as a diesel particulate filter at high space velocity and without a detrimental pressure drop. In addition, the combination of such a hierarchical structure with high thermal conductivity could give rise to unexpected results in the field of heterogeneous catalysis where the mass and heat transport limitations still need to be improved
