The present disclosure relates to a novel staged-synthesis method for introduction of various metals in the structure of zeolite frameworks by isomorphous substitution. This new method is based on a hydrothermal synthesis in which the metal addition to the precursor suspensions (gel) is delayed. This so-called 'staged-synthesis method' allows to obtain nanosized silanol highly homo-geneous crystalline zeolite structures with a control of the metal location.
