Metal-organic frameworks are believed to be one of the solutions in reducing CO 2 emissions. Ligand modification, which is one of the methods in optimizing the MOF structure, provides a good opportunity for the development of functional materials with better properties. Ligand functionality in gas separation is important because it provides an insight of the influence of the material topology. MIL-101 (Cr), which is a type of MOF, is composed of metal chromium and terephthalic acid as the linker. This MOF has been extensively researched for CO 2 capture applications. In this work, the functionalization of MIL-101 with 1,4-Benzenedicarboxylic acid (BDC) as the ligand was carried out by changing into 2,6-Napthalenedicarboxylic acid (NDC) ligand. The design and architecture of NDC, which has a double hydrocarbon ring, is expected to increase the pore and surface area of the MOF so that it can increase gas adsorption. The synthesis of the modified MOF was performed using solvothermal method and tested for the porous properties, morphology, structure, chemical functionalities and thermal stability by N 2 adsorption / desorption data, scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). The results show that MIL-101 NDC has better thermal stability, as it can maintain its structure up to the temperature of 350°C. The pore diameter measurement results also show a good diameter up to 4nm. The discovery structure of MIL-101 NDC which has excellent stability provides a good prospective adsorbent in CO 2 capture applications.
