Conversion of Protonated Magadiite to a Crystalline Microporous Silica Phase via a New Layered Silicate

Organic structure-directing agents are necessary to the formation of defined zeolitic structures; doing without the organic component can simplfy the reaction immensely. Such a transformation, of protonated magadiite to a new layered silicate, is reported herein. The picture shows the XRD patterns of as-prepared protonated magadiite and the product after simple hydrothermal treatment at two different temparatures. After calcination (500 °C) the final material has a surface area of 457 m(2) g(-1).
