Nanostructured metal oxides showing geometrically controlled shape are often shaped by the calcination of selected metal coordination complexes adsorbed on sacrificial polystyrene beads (PSB) in aqueous suspensions.The design of an alternative, more sustainable, method to guide the adsorption of titanium oxide precursors on sacrificial carriers into specific morphologies has been explored as part of a global strategy to produce new nano-engineered metal oxides.Among various titanium coordination complexes, ligands like β-diketones or β-ketoesters have been often investigated due to their chelating and stabilizing effect on the titanium. In particular, titanium coordination complexes like Titanium(IV)bis(ammonium lactato) dihydroxide and titanium diisopropoxide bis(acetylacetonate) have been largely applied in the fabrication of nanostructured titanium oxide films in last-generation photovoltaic devices.To …
