Abstract

Abstract : A HF free method for the controlled synthesis of nanosized TiO2 with a higher percentage of {001} reactive facets. Abstract : This is a report on the facet controlled synthesis of TiO2, which has been achieved using the acidic room temperature ionic liquids (AILs) 1-butyl-3-methylimidazolium hydrogen sulphate and 3-methyl-1-(3-sulfonyl propyl)imidazolium trifluoro methane sulphonate as the templating and hydrolysing agents. The effect of the change of concentration of the AIL, amount of the AIL and calcination temperature demonstrated good phase control and a higher number of exposed {001} facets in the TiO2 nanocatalysts with a higher photocatalytic activity.
