Rapid synthesis of MCM-41 and SBA-15 by microwave irradiation: promising adsorbents for CO2 adsorption

Abstract It is known that the world scenario one of constant search for sustainable technologies can reduce emission carbon dioxide (CO 2 ) in atmosphere. This because CO seen as main responsible increase generation greenhouse gases, which leads to global warming and climate change. The development efficient adsorbents capture a current challenge. MCM-41 SBA-15 were synthesized microwave reactor used this work. Microwave irradiation presents itself an easy synthesis strategy with less preparation time energy requirement. silica period was extremely reduced (1 h) at temperature 60 80 °C reactor, obtaining good textural chemical properties. adsorption isotherms performed 0, 25, 40 1 bar. present favorable results processes, showing pure by already obtains promising results, reaching maximum capacity 2.16 mmol g −1 bar—0 °C) fit Langmuir, DsL Toth models. Furthermore, adsorption, mesoporous also modified via impregnation branched polyethylene diamine (PEI) or tetraethylenepentamine (TEPA). worth mentioning steps improved properties silica. work opens new opportunities materials require optimizing adsorbent process.
