HYDROTHERMAL SYNTHESES AND STRUCTURAL CHARACTERIZATION OF ZEOLITE ANALOG COMPOUNDS BASED ON COBALT PHOSPHATE

Zeolite analogues containing transition metals are highly desirable fo r industrial processes. A generalized synthesis method has been develo ped and demonstrated to have the potential to generate many transition -metal-rich zeolite-type structures. The method has been used to make zeolite analogues based on cobalt phosphate with diverse chemical comp ositions and structure types, including some analogues never previousl y synthesized and some zeolite-like structures only previously known t heoretically. The concentrations of transition-metal atoms in the fram eworks can be controlled by varying the charge and geometry of the str ucture-directing amine molecules.
