Abstract: Provided herein is a novel silica-supported nickel nanocomposite and a novel one-pot solution combustion synthesis of that nanocomposite. The method allows the synthesis of small size nickel nanoparticles (e.g., 3 nm to 40 nm) for which a considerable percentage of nickel is inserted into silica, experiencing strong metal-support interaction. These exceptional physicochemical properties make them desirable for various industrial applications, such as electronic, heterogeneous catalysis as well as conversion and storage of energy.

Abstract: This invention relates to development of novel Cu-based nanocatalysts synthesized via one-pot solution combustion synthesis for CO2 hydrogenation to methanol. The novel Cu-based catalyst has exceptional activity for CO2 hydrogenation with high methanol selectivity in the reaction temperature range between 250° C.-350° C. The novel catalyst also exhibits excellent resilience to deactivation due to sintering.
