Evaporation-induced self-assembly synthesis of nanostructured alumina-based mixed metal oxides with tailored porosity.

The one-pot synthesis of nanostructured ternary mixed oxides is challenging due to the heterogeneous nature of the hydrolysis and condensation processes of all metal oxide precursors. In addition, the solvents and additives used can affect these processes too. Herein, we report the effect of different solvents (ethanol, 1- and 2-propanol, or butanol) and additives (citric acid or 1,3,5-triisopropylbenzene) used on the formation of binary and ternary alumina-based oxides, NiO-AlO, NiO-TiO-AlO, and NiO-ZrO-AlO in the presence of triblock copolymer Pluronic P123 used as a soft template.
