Estimating the term…
A process for preparing a mesoporous material, e.g., transition metal oxide, sulfide, selenide or telluride, Lanthanide metal oxide, sulfide, selenide or telluride, a post-transition metal oxide, sulfide, selenide or telluride and metalloid oxide, sulfide, selenide or telluride. The process comprises providing an acidic mixture comprising a metal precursor, an interface modifier, a hydrotropic or lyotropic ion precursor, and a surfactant; and heating the acidic mixture at a temperature and for a period of time sufficient to form the mesoporous material. A mesoporous material prepared by the above process. A method of controlling nano-sized wall crystallinity and mesoporosity in mesoporous materials. The method comprises providing an acidic mixture comprising a metal precursor, an interface modifier, a hydrotropic or lyotropic ion precursor, and a surfactant; and heating the acidic mixture at a temperature and for a period of time sufficient to control nano-sized wall crystallinity and mesoporosity in the mesoporous material. Mesoporous materials and a method of tuning structural properties of mesoporous materials.
A mesoporous material particulate having nano-sized, single crystal phase, wall crystallinity, a particle size between about 50 and about 500 nm, a BET surface area between about 50 and about 1000 m2/g, a pore volume (BJH) between about 0.05 and about 2 cm3/g, a monomodal uniform pore size (BJH desorption) distribution between about 1 and 25 nm, and optionally a wall thickness (2d/√3−PD, where d is the d-spacing and PD is the pore diameter) between about 2 and about 20 nm;
