摘要: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.

摘要:The invention relates to a method for preparing a hierarchical porous zeolite membrane and an application thereof, comprising the following steps: a mesoporous structure-directing agent is added to limit the growth of zeolite crystals, and self-assembled in the crystallization process to generate a mesoporous structure. Based on a seed crystal induced secondary nucleation mechanism, this method can realize one-step hydrothermal synthesis of hierarchical porous zeolite membrane with the advantages of mild and controllable synthesis conditions, simple process, good repeatability, reduced energy consumption and cost savings. The hierarchical porous zeolite membrane prepared by the method has good cut-off performance, and the cut-off molecular weight is adjustable between 200 to 500,000 Da.

摘要:A method for attaching silicon-containing compounds to a surface and for synthesis of hypervalent silicon-compounds is described. Attaching silicon-containing compounds to a surface comprises providing a silicon-containing compound having two or more leaving groups, and a first functional compound comprising at least one nucleophilic group, contacting the silicon-containing compound and the functional compound with a surface of a substrate having nucleophilic sites and exposing the silicon-containing compound, the functional compound and the surface of the substrate to microwave radiation.

标题 :Synthesis of hierarchical nanocrystalline zeolites with controlled particle size and mesoporosity

摘要:A one step synthesis of nanocrystalline zeolites ZSM-5 and Naβ from a single template system in high yield has been discovered. The size of individual nanocrystals, as well as mesopore surface area and pore volume can be controlled by adjusting the pH of the reaction mixture, as well as the hydrothermal treatment temperature and duration. The mesopore volume and size distribution show a dependence on particle size such that smaller particles lead to higher mesopore volumes and narrower pore size distributions.

摘要:Methods for making a Mo-nanosheet-CHA catalyst and Mo-meso-CHA catalyst. The method includes preparing an aqueous solution comprising one or more structure directing agents, mixing the aqueous solution with at least one silicon precursor and at least one aluminum precursor to provide a synthesis gel; recovering crystalline solids from the synthesis gel, wherein the crystalline solids consist of CHA zeolite crystallites; depositing a source of molybdenum onto the CHA zeolite crystallites to provide Mo-CHA zeolite crystallites having an average particle size of less than 200 nm in Mo-nanosheet-CHA and an average particle size > 500 nm in Mo-meso-CHA and containing a plurality of CHA zeolite pores; and carburizing the Mo-CHA zeolite crystallites at a temperature of 500°C to 900°C and a pressure of 80-100 kPa in the presence of methane (CHa) to form Mo carbide domains within the CHA zeolite pores. The Mo-nanosheet-CHA and Mo-meso-CHA catalysts are particularly useful for converting methane to aromatics.
