Synthesis of Pd-NiFe₂O₄/SiO₂ catalyst for thermal decomposition of methane to hydrogen

The aim of this work is to prepare a catalyst based on nickel which could be used as a catalyst for thermal decomposition of methane. Prepared catalysts will be studied in terms of their structure and catalytic activity. Catalytic activity will be studied by pyrolysis gas chromatography in the temperature range 300-500 grad C. In this study, a liquid mixture with uniformly dispersed Pd nanoparticles and Ni and Fe metal oxides will be prepared. The mixture of these nanoparticles will be deposited on a SiO₂ support. In this way, the two types of nanoparticles can obtain a coordinated distribution so that each Pd nanoparticle can be separated from each other by metal oxide nanoparticles around it and vice versa. This coordinated distribution creates a sufficient interface between Pd nanoparticles and metal oxides, where oxygen mobility significantly increases catalytic activity. Thus, the catalyst achieves high activity and sintering resistance. (authors)
