Abstract The biggest crisis facing mankind today is global warming which causes extreme climate change and eustatic sea level rise. The combustion of fossil fuel causes raising atmospheric CO2 concentration which is major source of greenhous eeffect. To effectively capture the CO2, our investigation focused on synthesizing practical CO2 capture materials like MOFs. In this work, we report synthesis, CO2 adsorption, working capacity, adsorption mechanism and chemical or physical stability of new type of heterodiamine functionalized MOFs for CO2 capture. To fully amine functionalize, we successfully synthesized extended version of MOF-74 which have 18.9 Å wide channels. After which we synthesized via postmodification Heterodiamine-functionalized metal-organic framework (MOFs), men’-Mg2(dobpdc), een-Mg2(dobpdc) and ipen-Mg2(dobpdc) (men’=N-methylethylenediamine, een = N-ethylethylenediamine, ipen = N-isopropylethylenediamine), which contain heterodiamines with primary and secondary amines. High working capacities are achieved at low regeneration temperatures. And these adsorbents have useful CO2 capture working capacities and good stability under humid conditions. These MOFs can be hopeful adsorbent for practical post-combustion CO2 capture process.
