Abstract: The synthesis process of titanium silicalite zeolite ETS-10 using commercial anatase and Na2SiO3 without the addition of fluoride ions was investigated. The synthesized ETS-10 was characterized by X-ray diffraction, scanning electron microscopy, thermogravimetric and N2 adsorption-desorption. The results showed that the prepared ETS-10 exhibits high BET surface area and pore volume of 333 m²/g and 0.21 cm³/g, respectively. ETS-10 is well crystallined with the morphology of truncated bipyramid and uniform particle size. The microporous structure with a uniform pore size of 0.7 nm is observed. Although the prepared ETS-10 contains a small amount of unreacted anatase, it shows similar adsorption performances in comparison with the common ETS-10. It also could be an effective adsorbent for CO2 capture from the flue gas stream due to the high selectivity of CO2/N2.
