The boron forms of the zeolite Beta (B‐Beta) and SSZ‐33 (B‐SSZ‐33) are treated with vapors of ZrCl4 in an attempt to substitute the framework boron for zirconium. The resulting materials Zr‐Beta and Zr‐SSZ‐33 are characterized by X‐ray diffraction (XRD), solid state NMR, FTIR, pyridine adsorption and Raman spectroscopies. In the case of zeolite Beta, Zr substitutes the B present in the framework nearly...
