The remarkable photocatalytic properties of titanium dioxide and the high adsorption capacity of the mesoporous materials were
combined to obtain active photocatalysts for the decomposition of Rhodamine 6G dye. The mesoporous TiO2 was obtained by
the controlled hydrolysis-condensation of titanium isopropoxide, using hexadecyl-trimethyl-ammonium bromide as template,
followed by calcination to remove the organic matter. Subsequently, this sample was doped with sodium wolframate and
platinum. The solids are highly porous, as proved by BET nitrogen adsorption. The photocatalytic tests were carried out at
different dye concentrations, catalyst dose and pH. The experiments showed good activities for both the initial support and doped
samples.
