  • Patent number: 8759245
    Abstract: The present invention relates to a method for preparing iron-containing porous organic-inorganic hybrid materials where the organic compound ligand is bonded to a central metal and has a large surface area and pores of molecular size or nano size, by irradiating microwaves instead of heat treatments such as the conventional electric heating, etc. as the heat source of the hydrothermal or solvothermal synthesis reaction, after reacting a metal or metal salt and organic compound to form crystal nuclei by a predetermined pre-treatment operation in the presence of a solvent. In another aspect, a method of the present invention further comprises the step of purifying the obtained porous organic-inorganic hybrid materials by treating them with inorganic salt. In particular, a method of the present invention is characterized by not using a hydrofluoric acid.

  • Publication number: 20120129684
    Abstract: The present invention relates to the use of solids consisting of a metal-organic framework (MOF) and having the units of the following formula (I): MmOkXILp as a nitrogen-oxide catalyst. The present invention also relates to devices for enabling the implementation of said use. The nitrogen oxides in question are nitrogen monoxide and nitrogen dioxide, collectively referred to as NOx. The MOF solids of the present invention are advantageously capable of removing nitrogen oxides from a liquid or gaseous effluent, for example from water, from the exhaust gases of a vehicle, factory, workshop, laboratory, stored products, urban air vents, etc., without any reducing agent and at a low temperature. The DeNOx catalysis is a major issue for our societies. The invention can be used for reducing or even avoiding the consequences for public health of the toxic NOx gases resulting from human activity.
