Layered Minerals, Mesoporous Oxides, Nanostructures
Design, synthesis, characterisation and catalytic applications of nanostructured materials:
- modified clays, hydrotalcite-derived mixed oxide catalysts, mesoporous oxides as supports for transition metal ions and organometallic compounds, heteropoly compounds
- complex nanocomposites based on intercalated layered compounds
The reactions of interest address environmental catalysis issues, and include combustion of volatile organic compounds, and liquid phase reactions such as Baeyer-Villiger oxidations with H2O2 or oxygen, aerobic oxidation of alkanes, olefins and aromatics, hydrogenations of alkynes and ketones under mild conditions.
- Synthesis and modification of cationic and anionic clay-derived and nanoporous materials under various conditions.
- XRD, surface area/porosity measurements, chemical analysis - ICP OES, TG/TDG/DTA, FTIR, UV-Vis, NMR, XPS, SEM/TEM.
- Design of novel catalysts for combustion of volatile organics based on composites of exfoliated clays and hydrotalcites prepared by inverse microemulsion.
- Design and synthesis of efficient pillared interlayered clay (PILC)-based catalysts for removal of chlorinated volatile organics.
- Design and synthesis of efficient hydrotalcite-derived catalysts for industrial scale combustion of volatile organic compounds.
- Discovery of a catalytic reaction capable of probing the spatial distribution of Al in the framework of mesoporous aluminosilicates.
- Determination of the nature of mixed Ti-Zr pillars in PILC catalysts.
- Broadening of the spectrum of heteropolyanions suitable for insertion into the layered double hydroxides by using the electrochemically reduced anionic species.
