Synthesis and Characterization of MOF-235 using Aluminum Pillared Clay for CO2 Adsorption

Reducing the concentration of the carbon dioxide (CO2) emission become one of the most urgent environment issues nowadays. By reducing the concentration of the CO2 will lead to the lowering the concentration of greenhouse gases. The source of CO2 emission can be concluded from natural source as well as from human source. For the natural source, CO2 emission occurs from the decomposition, ocean release, respiration and volcanoes. Furthermore, for the human source, the CO2 will emit from activities like cement production, deforestation and the burning of fossil fuels. One of the common technologies that had been use for reducing the CO2 concentration is by using carbon capture and storage (CCS). Usually, CCS method is used from large point sources such as power plants are one option for reducing CO2 emissions. Apart from CCS technique, the alternative method reducing of the CO2 concentration also had been studied. One of the methods is known as adsorption technique. However, the adsorption of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of capture materials with high adsorption performance and low capital cost are of paramount importance. Metal-organic frameworks (MOFs), a new class of crystalline porous materials constructed by metal-containing nodes bonded to organic bridging ligand shows a great potential as adsorbents or membrane materials in gas separation.
