Catalytic Processes for Clean Energy
Studies are focused on examination of polymer-palladium nano-composites as heterogeneous catalysts in liquid phase hydrogenation of organic compounds with C=O, C-OH as well as double and triple unsaturated C-C bonds (2-ethylanthraquinone, acetophenone, maleic and fumaric acids, 2-butyne-1,4-diol). The aim is to prepare catalysts with Pd particles of nano-scale and to examine the role of specific polymer properties (hydrophobic character, electroactive properties, swelling ability) in reactivity of Pd-species (access of Pd-particles) and selectivity of hydrogenation reaction. Polymers in the form of powder: poly(4-vinylpyridine), polyaniline, polypyrole, micro and macro-porous polyesters resins, and in the form of film deposited onto SiO2 grains are used. Another interest of my group is transesterification as a method of bio-fuels production by using acid and base catalysts.
