Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="cjce21816-sec-0001" sec-type="section"> <p>High purity titanium dioxide (TiO₂) nanoparticles were synthesised via a modified sol–gel method using titanium tetraisopropoxide (TTIP). XRD analysis showed that the synthesised product was TiO₂ powder in anatase form. The sample possessed a relatively high surface area of 75.64 m²/g. The typical TEM images suggested that the crystalline phase product was composed of fine particles with dimensions between 17 and 20 nm. The synthesised material was used as a photocatalyst for the removal of mercaptans from gas–oil. The result showed that up to 78% of the mercaptans in gas–oil was removed using the synthesised TiO₂ photocatalyst.</p> </sec> </abstract>
