Synthesis, characterisation and catalytic testing of pillared clays and lanthanum exchanged ZSM-5 for hydrocarbon conversion
… that pillaring has on the physical and catalytic properties of some smectite clays. The effect of using a hydroxy-Al solution to pillar a predominantly octahedrally ,substituted clay (montmorillonite) and a tetrahedrally substituted clay (beidellite) were compared. The effects of pillaring …

Supramolecular templating of mesoporous zirconia-based nanocomposite catalysts
… interest in acid catalysis because its surface acidic properties can be flexibly tailored. However, the zirconia-based materials typically have low surface areas and poorly controlled textural properties. This thesis reports on the design and synthesis of nanostructured zirconia-based materials …

Composite Gel Polymer Electrolyte for Lithium Ion Batteries
… separator using solution casting technique. In acidic CGPE, the mixture of acid treated TiO<sub>2</sub> and neutral SiO<sub>2</sub> nano particles played the role of the charge modified nano fillers with enhanced hydroxyl groups. The mixture of neutral TiO<sub>2</sub> nano particles with basic …

SYNTHESIS AND CHARACTERIZATION OF SUPPORTED SOLID ACID CATALYSTS FOR CONVERSION OF GREEN SEED CANOLA OIL TO BIODIESEL
… reaction conditions. Porous oxide material with acidic properties was determined to be suitable for heterogenization of HPW. However, complete disintegration of HPW at loadings of high concentrations (55 and 65 wt %) was observed on the γ-Al2O3 surface and hence, reduced the catalytic activity. …

GREEN CATALYTIC STRATEGIES FOR THE PRODUCTION OF BIOBASED BUILDING-BLOCKS
… nature of the support they can have different acidic/basic or wettability properties making them very versatile in organic synthesis. Deep characterization was performed on the catalytic system to enlighten the relationship between physicochemical properties of the catalysts with their …
