Abstract
Four different fluorinated surfactantbased systems were used as template for the synthesis of highly ordered TiO2 mesoporous materials with largepore wormhole structures The calcined materials exhibit large pore diameters up to 59 nm high surface areas 900–1180 m2 g−1 pore volumes 090–125 cm3 g−1 and thick pore walls 46–77 nm depending of the synthesis route It is established that the selfaggregation behavior of fluorinated amphiphile systems can be manipulate and provides a rich phase behavior to obtain wellorganized titania sieves with adjustable pore size and surface topography By comparison to titania and silica sieves obtained by the same procedure it can be established that there is a deep interaction between head groups of fluorinated surfactants and TiIViPrO4 showing that the inorganic precursor has a great influence on the properties of the final materialsThe authors acknowledge Universidad Nacional del Sur PGI 24/ZQ07 Concejo Nacional de Investigaciones Científicas y Técnicas de la República Argentina CONICET PIP11220100100072 Education Audiovisual Culture Executive Agency European Commission EMUNDUS18 and Xunta de Galicia for their financial support Project No PXI20615PN PM is an adjunct researcher of CONICET
