Metal‐Organic Frameworks Derived Porous Carbons: Syntheses, Porosity and Gas Sorption Properties

Abstract

Porous carbon materials derived from metal-organic frameworks (MOFs) have been brought into stage due to the intrinsic advantages of MOFs such as high porosity and tailorable structure diversity, which might provide infinite possibility in producing porous carbons with diverse structures and various decorations. Inherited from MOFs, the porosity in carbon materials is an important factor to evaluate the performances of porous carbons (e.g. gas sorption properties, electrochemical and catalytic behaviors). Factors that affect the porosity of porous carbon materials are mainly focused on the porosity of pristine MOFs, additives and conducting conditions. However, during past decades there were still no systematical reports on the influence factors of porosity in MOFs derived porous carbon materials and corresponding gas sorption properties. In this review, we will summarize the performances of MOF-derived carbon materials (i.e. non-doped porous carbons, heteroatoms doped porous carbons, metal/metal oxide decorated porous carbons) and give a detailed discussion about the connections between the properties and four major effects (calcination temperature, loading of additional precursor, post-synthetic treatment as well as intrinsic properties of MOFs).

Study on the structure activity relationship of the crystal MOF-5 synthesis, thermal stability and N2 adsorption property

“…Therefore, this specific structure makes MOF-5 large surface area and exceptional pore volume. It has rapidly developed as a hotspot in the crossing fields of energy, chemistry, materials and life science [6]. MOF-5 was mainly synthesized through hydrothermal [7], solvothermal methods [8], microwave-based [9] and sonochemical [10].…”

Synthesis of Highly Stable Porous Metal‐Iminodiacetic Acid Gels from A Novel IDA Compound

“…The isotherms exhibit a high gas uptake at the relative pressure (p/p 0 ) less than 0.02, a flat course at the middle relative pressure, and sharp gas adsorption at the high relative pressure, which indicate a significant microporosity and macroporosity in the MIG aerogels. The BET specific surface area results are found to be 760 and 430 m 2 •g 1 for MIG1 and MIG2 aerogels, respectively. Owing to their flexible structure in their networks, MIGs exhibit relatively lower specific surface area compared with other metal-organic gel counterparts reported.…”

“…[1] Owing to their unique structures, MOFs can be utilized in versatile applications such as adsorption, [2] ion exchange, molecular recognition, catalytic, and optical, [3] electrical, magnetic, chiral separation fields. [4] MOFs are commonly in the form of powdery crystal.…”

Recent Advances on Metal‐Organic Frameworks in the Conversion of Carbon Dioxide

“…[ 26 ] In this point, our group and other researchers have developed sorts of MOFs for capturing CO 2 , which show remarkable CO 2 capacity and selectivity. [ 27‐36 ] The high capacity of CO 2 makes these MOFs to be potential candidates for CO 2 conversion.…”
