Abstract
Carbon dioxide reforming of methane is an promising route for synthesis gas production, especially over nanostructured catalysts. Authors describe nanocatalyst development using the sonochemical method for dry reforming of methane with the goal of determining the most efficient nanocatalyst.
Researchers consider the effect of Ni metal content on the properties of the ZSM-5 supported nanocatalysts. They fabricated the Ni/ZSM-5 nanocatalysts with the assisted traditional impregnation method via ultrasound irradiation. The nanocatalysts were characterized with XRD, FESEM, TEM, BET and FTIR. Comparison of XRD patterns suggests that the peaks related to NiO become sharper by increasing metal content over the support. In the case of nanocatalysts with lower metal content (3% and 8%), the beneficial influence of ultrasound assisted procedure became more pronounced.
