Nowadays, energetic need are mainly covered by fossil fuels, and the poorly handling the emissions containing CO2, CH4, and NOx are responsible for the global warming. Among all the potential solutions, physical adsorption is very outstanding due to its low regeneration cost, high selectivity, thermal stability, and high adsorption capacity. Various solid adsorbents have been investigated to meet the increasing requirements of separation and purification technologies for carbon dioxide capture in the contexts of post-combustion (CO2/N2) and natural gas upgrading (CO2/CH4). Metal-organic frameworks (MOFs) draw lots of attention in this field in past decades, high capacity and selectivity, controllable pore size, and dramatically variability are the brand marks, however, one main drawback is instable to thermal, humidity, and time. Whereas, activated carbon materials are extremely stable to many industry conditions. Thus, we want to develop activated carbon from MOFs while maintaining advantages of MOFs and make it more stable.

In this presentation, we will report novel porous carbon adsorbents derived from MIL-100 Al3O(btc)2(OH)(H2O)2•X (btc = benzenetricarboxylate; X = encapsulated species, i.e., H2O, etc.) using three different methods, denoted as Al-100 derived activated carbons (AACs). We will define a set of selective parameters to prove AACs are promising adsorbents for industry applications. Multiple characterization methods are applied, such as, thermogravimetric analysis (TGA), X-ray diffraction (XRD), Raman Spectra, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The highest specific surface area obtained is 1097 m2 g-1 with 0.82 cm3 g-1 pore volume. The highest CO2 capacity obtained is 6.53 and 4.80 mmol g-1 at 273 and 298K, respectively. We will also report the high ideal adsorbed solution theory (IAST) selectivity of CO2/N2 and CO2/CH4 and adsorption breakthrough simulation results                                              Self-template Porous Carbons Derived from Metal-organic Framework: Synthesis, Characterization and Adsorption Properties
