METHODS FOR SYNTHESIS OF HIERARCHICALLY ORDERED CRYSTALLINE MICROPOROUS MATERIALS WITH LONG-RANGE MESOPOROUS ORDER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240009660 titled 'METHODS FOR SYNTHESIS OF HIERARCHICALLY ORDERED CRYSTALLINE MICROPOROUS MATERIALS WITH LONG-RANGE MESOPOROUS ORDER

Simplified Explanation

The patent application describes methods for synthesizing hierarchically ordered zeolites and zeolite-type materials with a high degree of well-defined long-range mesoporous ordering. These methods involve base-mediated reassembly by dissolving the parent material to the level of oligomeric structural building units and minimizing or avoiding amorphization/structural collapse. The dissolution and self-assembly process is controlled to produce hierarchically ordered zeolites and zeolite-type materials.

  • The methods involve base-mediated reassembly of parent materials.
  • Dissolution of the parent material is done to the level of oligomeric structural building units.
  • Amorphization/structural collapse is minimized or avoided.
  • The dissolution and self-assembly process is comprehensively controlled.
  • The resulting materials have a high degree of well-defined long-range mesoporous ordering.

Potential applications of this technology:

  • Catalysts in various chemical processes.
  • Adsorbents for gas separation and purification.
  • Molecular sieves for selective adsorption.
  • Support materials for drug delivery systems.
  • Zeolite membranes for separation processes.

Problems solved by this technology:

  • Lack of well-defined long-range mesoporous ordering in zeolites and zeolite-type materials.
  • Difficulty in controlling the dissolution and self-assembly process.
  • Amorphization or structural collapse during synthesis.

Benefits of this technology:

  • Improved catalytic performance due to well-defined long-range mesoporous ordering.
  • Enhanced selectivity and efficiency in gas separation and purification processes.
  • Better control over the synthesis process, leading to reproducibility and scalability.
  • Potential for the development of new materials with tailored properties.
  • Increased stability and durability of zeolite membranes.


Original Abstract Submitted

methods for synthesis of hierarchically ordered zeolites and zeolite-type materials are provided. synthesized hierarchically ordered zeolites and zeolite-type materials formed according to the methods herein possess a high-degree of well-defined long-range mesoporous ordering. the methods include base-mediated reassembly, by dissolution of the parent material to the level of oligomeric structural building units of the parent material, and minimizing or avoiding amorphization/structural collapse. the dissolution and self-assembly is comprehensively controlled to produce hierarchically ordered zeolites and zeolite-type materials according to the methods herein.
