Preferred Method: The MCF-R is mixed MOF precursor using ultrasonic method, electromagnetic method, or a reflux method, The MCF-R-MOF composite is crystallized using an electric heating method, ultrasonic method, electromagnetic method or electrochemical method. EXAMPLE - Pluronic block-copolymer (PI23) (1.62 g) and acetic acid (0.8 g) (99%) were dissolved in water (33.33 g) to form a first solution, which was heated to 60 degrees C. Simultaneously, sodium silicate (Na2Si307) (0.23 g) containing silica (27%) and triethoxybutyronitrile (TEBN) (2.67 g) were completely dissolved in water (33.33 ml) to form a second solution. Subsequently, the two solutions were mixed and then stirred at 60 degrees C for 1 hour to form a mixed solution. The mixed solution was hydrothermally synthesized at 100 degrees C for 12 hours to prepare MCF-CN. In order to remove PI23 from the prepared MCF-CN and to oxidize CN group of the MCF-CN, MCF-CN (l g) was mixed with sulfuric acid (48%) (120 ml) and then stirred at 95 degrees C for 1 day to form gigantic mesoporous cellular foam (MCF-CO2H). MCF-COOH (0.2 g) and ferric nitrate (0.46 g) hydrate (Fe(NO3)3.9H2O) were mixed with water, and then irradiated with ultrasonic waves for 30 minutes to form a first mixed solution. Subsequently, 1,3,5-benzenetricarboxylic acid (BTC) (0.16 g) was added to the first mixed solution, and then stirred for 10 minutes to form a second mixed solution. The second mixed solution was reacted in a Teflon microwave reactor at 140 degrees C for 30 minutes to produce organic-inorganic nanoporous composite.
