Abstract: A method for preparing a precious metal doped organic-inorganic mesoporous material by introducing a lipophilic group into a mesoporous structure and highly dispersing a precious metal as an active metal into cavities of a porous material is provided, and a method for removing vapor- or particle-phase hazardous organic materials using the precious metal doped organic-inorganic mesoporous material as a catalytic material is provided. A method for preparing a precious metal doped organic-inorganic mesoporous material comprises the steps of: (1) stirring a precious metal compound, a chelate agent, a polymer surfactant, and an organic silane compound to prepare a mixture; (2) subjecting the mixture to a hydrothermal reaction to prepare an organic-inorganic silica mesoporous material into which a precious metal is dispersed; and (3) firing the organic-inorganic silica mesoporous material. The precious metal is selected from palladium(Pd), platinum(Pt), ruthenium(Ru), rhodium(Rh), silver(Ag), gold(Au), osmium(Os), iridium(Ir), or mixtures thereof. The precious metal is contained in the organic-inorganic mesoporous material in an amount of 0.1 to 20 wt.% based on the total weight of the organic-inorganic mesoporous material. The precious metal compound is a precious metal chloride. The chelate agent is a poly alcohol selected from polyethylene glycol, polypropylene glycol, and ethylene glycol. A method for removing hazardous organic materials comprises contacting the prepared precious metal doped organic-inorganic mesoporous material with hazardous organic materials, thereby subjecting the hazardous organic materials to an oxidation reaction. Further, the polymer surfactant is a block-copolymer of poly ethylene oxide-poly propylene oxide-poly ethylene oxide.

Abstract: An organic-inorganic porous adsorbent and a method for producing the same are provided to increase the amount of adsorbed moisture and facilitate the desorption of moisture even at a relatively low temperature, by using a copper-containing porous organic-inorganic hybrid. A moisture adsorbent is formed by using a copper-containing porous organic-inorganic hybrid. The moisture adsorbent is prepared through a reaction between a copper precursor and an organic ligand such as terephthalic acid or benzene tricarboxylic acid, under a condition in which acid, base, or salt thereof is not added. The moisture adsorbent has a surface area of 1000-10,000 m^2/g and a pore volume of 0.7-10 mL/g. The moisture adsorbent desorbs 80 wt% of adsorbed moisture at a moisture desorption temperature of 60-100°C within 5 minutes. Further, The moisture adsorbent desorbs 90 wt% of adsorbed moisture at a moisture desorption temperature of 60-80°C within 5 minutes.
