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 mate- rials 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）.展开更多

The C ls, O ls and Si 2p core-level spectra and the RHEED patterns indicate the formation of 3C-SiC.展开更多
