The preparation of visible light driven photocatalysts for photocatalytic water splitting has been achieved by a CO₂ free, low cost and simple novel method. Combination of peroxide based route with organic free solvent and titanium nitride, carbon free precursor and air and mois…
Organic contaminants from industrial and/or domestic effluents may be harmful to humans directly or indirectly by degrading the quality of the aquatic environment. Consequently these contaminants must be reduced to levels that are not harmful to humans and the environment before…
Titanium dioxide, TiO₂, materials have received much attention in recent years due to their potential use as intercalation negative electrodes for rechargeable lithium-ion batteries. The aim of this doctoral work was to synthesise and characterise new titanium dioxide nanomateri…
In the present research, a novel method, namely sol-gel/laser-induced technique (SGLIT), has been developed to generate nano-structured TiO2-based films. The TiO2 films based on unloaded (pure) TiO2, Ce-TiO2, W-TiO2 and Ag-TiO2, have been investigated in attempt to stabilise the…
The subject of this thesis is the fabrication, structure and optical behavior of Al2O3-TiO2 nanolaminate thin films. Al2O3-TiO2 nanocomposites are of current interest for optical, catalytic, and sensor applications. Five nanolaminate architectures were grown on unheated substrat…
Mineral dust represents one of the largest mass fractions of the global aerosols. Iron oxide and titanium dioxide are components of mineral dust that are found in appreciable amounts. Ammonia from livestock, agriculture, industry, and waste treatment sources is an important air …
