Mesoporosity development of TiO₂ nanoparticles depending of applied synthetic method

Because of the use of triblock copolymer, pluronic F127 as a structure directing agent, in the preparation of TiO₂ nanoparticles, great properties could be obtained. The challenge is to use a variety of synthetic method, following the same recipe, and develop textural properties of the end product, namely nanoporous TiO₂ nanoparticles. Thus, in order to find out more about textural features of TiO₂ nanoparticles, the reaction mixture have been treated in three different ways as: magnetic stirring, ultrasonics, and liquid plasma. The resulted white titania powders were characterized and their textural properties have been compared. It has been concluded that the same used titania source/F127 weight ratio led to TiO₂ nanoparticles with different textural characteristics.
