Abstract

Catalysts based on metal nanoparticles (Cu or Ni) supported on carbonaceous materials (activated carbon or carbon nanotubes) and molecular sieves will be prepared, characterized and tested as catalysts in the oxidation of glycerol and acetol. Some methods of synthesis of metallic nanoparticles will be tested (wet impregnation, polyol-based method for the synthesis of Cu nanoparticles and the chemical reduction with N2H4 for the synthesis of Ni nanoparticles, ³-irradiation). Solids used as support will undergo oxidative and/or thermal treatments. The materials will be characterized by appropriate techniques, among which nitrogen adsorption, transmission electron microscopy, X-ray photoelectron spectroscopy, elemental analysis, X-ray diffraction, temperature programmed reduction and titration of surface functional groups. The catalysts will be used in catalytic oxidation of glycerol and acetol in the presence of oxygen, synthetic air or hydrogen peroxide. The oxidation products, especially glyceric acid and dihydroxyacetone, will be quantified by high performance liquid chromatography. The results will be related to the characteristics identified for the catalysts in terms of metal type, metal particle size and surface type of the substrate. According to the results, the reaction conditions must be varied. Adequate catalytic activity of the materials developed in this work could be an interesting alternative for the replacement of catalysts based on Au, which would lead to greater economic feasibility for the conversion of glycerol into higher value-added products through its oxidation.
