Synthesis and application of layered titanates in the photocatalytic degradation of phenol

This study proposes a direct synthetic route to single titanate sheets through the mild and versatile conditions of the “chimie douce”. The stages of the production include the complexation of the titanium alkoxide precursor by benzoic acid, the formation of titanium oxo-clusters and their controlled transformation into single sheet titanates during the hydrolysis stage. The resulted material appears to be an excellent precursor for self -organized TiO2 nanotubes formation which presents an excellent activity as photocatalyst in the photo-degradation of phenol.
