چکیده

Abstract: 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 by means of xrd, tga/dsc and bet/bjh analyses. according to bet/bjh analyses, prepared composites had mesoporous phase and increasing of calcination temperature give rise to decreasing surface area and pore diameter of nanoparticles. these analyses showed sample prepared at 1100 ◦c has slit like pores.
