Embodiment Construction

[0044] In the following detailed description of the invention, reference is made to Examples, including Tables and Figures.

[0045] Throughout the description, when reference is made to zeolites, this is meant to include zeolites, zeolite-like materials and zeolites unless specifically mentioned otherwise.

[0046] By zeolite, zeolite-like and zeolite-like particles is meant zeolite, zeolite-like and zeolite-like crystals or zeolite, zeolite-like and zeolite-like materials.

[0047] By the term zeolitic is meant a material that does not contain silicon. Examples of zeolite-like materials are silicon-free materials such as aluminum phosphate (AlPO4) molecular sieves, known as AlPO's. The phosphorus compound may be selected from the group consisting of phosphoric acid, phosphate salts and mixtures thereof. By the term "phosphate" is meant salts of phosphate, monohydrogenphosphate and dihydrogenphosphate.

[0048] In the present application, a new process for the production o...

Abstract

Disclosed herein is a method for producing a zeolite, zeolite-like or zeotype structure with selective formation of metal, metal oxide or metal sulphide nanoparticles and / or clusters inside the zeolite, zeolite-like or zeotype structure.

Description

technical field [0001] The present invention relates to a zeolite for the selective formation of metal, metal oxide or metal sulfide nanoparticles and / or clusters within a zeolite, zeolite-like or zeotype structure, Zeolite-like or zeolite-like structure methods. Background technique [0002] Given the current environmental challenges, there is an urgent need to develop a more sustainable chemical industry through more efficient chemical transformations and through the development of new highly selective and cost-effective catalysts. One approach to improve the catalytic performance of supported metal catalysts is to increase the active metal surface by synthesizing small metal nanoparticles (typically <10 nm in diameter). However, small nanoparticles are often prone to sintering, which reduces catalytic activity over time. Therefore, the development of sinter-stable heterogeneous nanoparticle catalysts is of great importance but poses great challenges. [0003] Zeolit...
