There is disclosed a method for preparing a metal-cation-deficient crystalline borosilicate, which method comprises: (1) preparing a mixture containing an oxide of silicon that is substantially free of metal cations, an oxide of boron, ammonium hydroxide, alkylammonium cation or a precursor of an alkylammonium cation, and water; and (2) maintaining the mixture at suitable reaction conditions to effect formation of the borosilicate. There are also disclosed the crystalline borosilicate that results from the above-described method of preparation and uses of that borosilicate. |
