A new TiO2/SiO2 nanocomposit was synthesized via a sol–gel method. Thermal phase transformation studies of the as-prepared composite were carried out to 1100 ◦C bymeans of XRD, TGA/DSC and BET/BJH analyses. According to BET/BJH analyses, prepared composites had mesoporous phase and increasing of calcination temperature giverise to decreasing surface area and pore diameter of nanoparticles. These analyses showed sample prepared at 1100 ◦C has slit-like pores.
