Abstract

A method is described for forming an aluminosilicate-zeolite layer on an aluminum-containing substrate by in situ direct crystallization. Aluminum-rich aluminosilicate-zeolite coatings on aluminum-containing metal substrates obtained by this method are advantageous, for example, in sorption-based fields of application, such as heterogeneous catalysis, in separation and cleaning processes, in sorption heat pumps, in conjunction with immobilized catalysts and in microreaction technology.
