Abstract
The present disclosure relates to a novel method for introducing various metals in the structure of zeolite frameworks by isomorphous substitution. This new method is based on a hydrothermal reaction of the metal with the zeolite. This method allows obtaining zeolite with a structure and with control of the metal location.
