N2 - ETS-4 had attracted more and more attentions for many researchers because of its potential properties in adsorption, gas separation, and catalysis, which has octahedral-tetrahedral structure with the potential properties that were different from the conventional zeolite materials. The preparation and crystallization of ETS-4 with small pores had been reported by many researchers. In this paper, titanosilicate ETS-4 sieves with the Sr and Ni modification were prepared by hydrotherrmal method using the titanium trichloride and tetraethoxysilane as the precursors. The properties and morphology of the materials were also characterized by XRD, SEM and PSA techniques. The Sr and Ni doping could improve the N 2 and CH 4 adsorption capacity of ETS-4. The N 2 and CH 4 adsorbance increased in the pressurization process for ETS-4-Sr and ETS-4-Ni, but no significant change in N 2 and CH 4 adsorbance with the pressure increasing was observed over the ETS-4 sample. At the pressure of 1200 mmHg, the N 2 adsorbances for ETS-4-Sr and ETS-4-Ni were 4.2 and 3.9 times as that of ETS-4 sieve, respectively. Summary, the metal ion doping (Sr 2+ and Ni 2+) can improve the adsorption performance of ETS-4 greatly.
