Abstract
The present invention relates to a method of post-synthetic downsizing zeolite-type crystals and/or agglomerates thereof to nanosized particles, and in particular a heating-free and chemical-free method. The present invention also relates to nanosized particles of zeolite-type material capable of being obtained by the method of the invention and to the use of such particles as a catalyst or catalyst support for heterogeneous catalyst, or as molecular sieve, or as a cation exchanger.
Claims11
Method of post-synthetic downsizing zeolite-type crystals and/or agglomerates thereof to nanosized particles of zeolite or zeolite-like, consisting of a heating-free and chemical-free application of a static pressure to said zeolite crystals and/or agglomerates, wherein the pressure is comprised between 1 MPa and 2000 MPa and the duration of the pressing is comprised between 1 and 60 minutes.
