Controlled growth of titania nanospheres in supercritical carbon dioxide using a novel surfactant stabilised precursor

Abstract

Titania nanospheres have been synthesised via the controlled hydrolysis of a mixture of novel precursor [Ti(OPri)3(Krytox)]n and titanium (IV) isopropoxide, [Ti(OPri)4], in supercritical carbon dioxide (sc-CO2). The use of sc-CO2 in the reaction, eliminates the need for organic solvents, optimises manufacturing efficiency and produces materials with tailored properties; additionally the use of the functionalised precursor [Ti(OPri)3(Krytox)]n, during co-hydrolysis with [Ti(OPri)4], gave a significantly narrower particle size distribution for the products than when the functionalised compound was not present.
