Recent studies in the evaluation of greenhouse effect show that the atmosphere contains steadily more toxic molecules that are very difficult to extract from the environment through the natural cycle.[1] Among these polluting agents, specifically carbon dioxide accumulates and it is the main cause of processes such as global warming. Subsequently, new scientific challenges are necessary to solve this problem.

Porous adsorbent materials, such as zeolites, alumina silica or activated carbon, have a lot of applications in the gas capture sector due to their extraordinary properties and characteristics. Though, metal organic frameworks (MOFs) have recently been triggering great interest in the field of gas capture. They expose a great deal of advantages in comparison with other more common materials used in this field, including carbon capture properties and easy fabrication. Permanent porosity, large volume of pores, large specific surface area and high thermal stability are some of the properties that MOFs exhibit.[2,3]

In this work, the synthesis and characterization of different HKUST-1/GO materials are analyzed in order to reach maximum CO2 capture. Synthetic procedure has been optimized using mechanochemical synthesis to respect the green chemistry standards avoiding the use of damaging solvents in the whole process. On the other hand, the most efficient amount of GO added to the samples is determined and quantified due to capture the maximum amount of CO2. Additionally, the corresponding characterization of HKUST-1/GO samples have been analyzed using IR spectroscopy, Thermogravimetry and X-Ray Diffraction, among others.
