Synthesis of Co-Silicalite-1 from a layered silicate

Abstract

Co-Silicalite-1 (Co2.3Si93.7O192) was synthesized from Co2+ ion exchanged magadiite. The characteristics of Co-Silicalite-l were investigated by using X-ray powder diffraction, IR spectroscopy, surface area measurement, NH3 temperature programmed desorption, and electron microprobe analysis. The measurements indicate that Co2+ ions replace SP ions in the Silicalite-l framework. The orthorhombic framework structure of calcined Co-Silicalite-l has been determined.
