Abstract
The invention concerns a method for manufacturing nanoporous metal oxide or metal active sites frameworks in which the metal oxide precursor is distributed into the framework in the form of a metal soap surfactant. The invention also covers a nanostructure framework comprising metal oxide active sites which are evenly distributed in the framework.
Claims17
A method for manufacturing a nanoporous framework containing metal oxide active sites using a metal soap surfactant as a metal oxide precursor to incorporate metal oxide sites into the nanoporous framework, the method comprising:
- (A) preparing a solution of a metal soap surfactant, wherein the metal soap surfactant is a laurate, stearate, palmitate, or caprylate of a metal selected from the group consisting of magnesium, calcium, strontium, barium, chromium, manganese, iron, cobalt, nickel, copper, zinc, zirconium, ruthenium, rhodium, palladium, silver, aluminium, titanium, silicon, indium, tin, thallium, lead, bismuth, lanthanum, cerium, samarium, europium, terbium, dysprosium, homium, erbium, and mixtures thereof,
- (B) mixing the metal soap surfactant solution with a condensing framework,
- (C) curing the mixture for forming a stable organic metal-centre/inorganic porous composite,
- (D) removing the soap by heat and/or chemical treatment thereby forming a metal oxide nanoporous framework.
