Abstract
The invention provides a method for synthesizing a mesoporous zeolite ETS-10 containing a metal without a templating agent. The method according to the invention comprises the steps of: mixing a silicon source with a NaOH solution to obtain a mixed solution so that the content of Na2O in the mixed solution is 10.0% to 20.0% by weight; adding a KOH or KF solution so that the content of K2O is 10.0% to 25.0% by weight and stirring it well; adding a titanium source solution and stirring it well; adding a precursor compound containing metal Ni and/or Co and stirring it well; and subjecting it to a crystallization reaction to obtain the mesoporous zeolite ETS-10. The mesoporous zeolite ETS-10 obtained by the invention has a specific surface area of 320 to 420 m2/g, a mesoporous volume of 0.11 to 0.21 cm3/g, and thus can be used as a catalyst and a support thereof in synthesis industry for macromolecular fine chemicals.
