Structural characterisation and mechanical stability of titanium substituted me...
P.C. Galacho; M.M.L. Ribeiro Carrott; J. Valério; P.J.M. Carrott; J.M. Valente NabaisMesoporous silica and titanium SBA-15 samples with different Si/Ti molar ratio were prepared by direct one-step synthesis under strongly acidic hydrothermal conditions. The materials were characterised by X-ray diffraction, nitrogen adsorption at 77K. The Si/Ti values of the final calcined materials were determined by ICP analysis. It was found that all samples presented 2-D hexagonal structures with high degre...
