Surface-modified zeolites and methods for preparing surface-modified zeolites are provided. A hybrid polymer formed from a silicon alkoxide and a metal alkoxide, a co-monomer, or both, is contacted with a zeolite suspension. The zeolite suspension comprises a sodium-, an ammonium-, or a hydrogen-form zeolite and a solvent. The hybrid polymer and zeolite suspension are contacted under conditions sufficient to deposit hybrid polymer on external surfaces of the zeolite to form a treated zeolite. Solvent is removed therefrom. The treated zeolite is dried and calcinated to form a dried and calcinated treated zeolite. Forming of the zeolite suspension and the contacting, removing, drying, and calcinating steps are provided in one selectivation sequence to produce a surface-modified zeolite from the ammonium-form zeolite and the hydrogen-form zeolite. If the dried and calcinated treated zeolite is a sodium-form zeolite, the sodium is exchanged with ammonium and then additionally dried and calcinated.
