摘要:The present application discloses a method of forming an inorganic macroporous material. In some embodiments, the method includes: providing a sample of organic polymer particles having a particle size distribution of no greater than about 10%; forming a colloidal crystal template of the sample of organic polymer particles, the colloidal crystal template including a plurality of organic polymer particles and interstitial spaces therebetween; adding an inorganic precursor composition including a noncolloidal inorganic precursor to the colloidal crystal template such that the precursor composition permeates the interstitial spaces between the organic polymer particles; converting the noncolloidal inorganic precursor to a hardened inorganic framework; and removing the colloidal crystal template from the hardened inorganic framework to form a macroporous material. Inorganic macroporous materials are also disclosed.

标题:Porous inorganic oxide materials prepared by non-ionic surfactant templating route

摘要:A method for the preparation of new semi-crystalline, porous inorganic oxide compositions possessing uniform framework-confined mesopores in the range 2.0-10.0 nm. The method uses an interaction between various nonionic polyethylene oxide based surfactants (N DEG ) and neutral inorganic oxide precursors (I &squ& ) at ambient reaction temperatures. The materials formed exhibit a disordered assembly of worm-like channels of regular diameter owing to the specific mechanism of self-assembly, producing highly stable materials and particles incorporating large numbers of the channels. This (N DEG I DEG ) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the template can be achieved through solvent extraction where the solvent may be water or ethanol.

摘要:A method for the preparation of new quasi-crystalline, porous inorganic oxide compositions formed in the presence of fluoride ion possessing a disordered assembly of worm-like channels. The method uses an interaction between various nonionic polyethylene oxide based surfactants (N DEG ) and neutral inorganic oxide precursors (I DEG ) in an aqueous solution and then the formation of dispersed particles in the aqueous solution in the presence of fluoride. This (N DEG I DEG F-) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the template can be achieved through solvent extraction where the solvent may be water or ethanol.
