Description
Cost efficient and long-term stable catalysts are in great demand for the CO2 hydrogenation to methane and C2 compounds, a key process in CO2 conversion into useful chemicals and fuels. Ni supported on oxides appear as promising catalysts for this reaction but still suffer from low activity at low temperature (< 300 °C) and fast deactivation. The BIZECO2 project falls within this context and aims to develop new catalysts containing specific bimetallic NiFe active sites promoting CO2 activation. Recently, the development of a new methanation catalyst concept based on the synthesis of Ni-doped ceria nanoparticles containing Ni ionic sites enabled to obtain a very high specific activity for the desired reaction. The aim of this project is to further develop this concept by verifying whether this is a more general trend that could be applied to other types of oxides. Metal-containing zeolites, important inorganic crystalline materials owing to their adsorptive and catalytic properties, are positioned to significantly contribute to the achievement of these goals. Recently, specific synthesis protocols allowed to directly insert a wide range of heteroelements within zeolite framework offering the possibility to apply it to bimetallic systems. We therefore propose the synthesis using high-throughput automated system, advanced characterization and catalytic evaluation of NiFe-MFI nanozeolites for CO2 methanation
