The metal-organic frameworks [MOF-525, Zr6O4(OH)4(TCPP-H2)3; MOF-545, Zr6O4(OH)4(TCPP-H2)2], have been synthesized and conducted for CO2 adsorption. MOF-525 and -545 are composed of porphyrin linked by either Zr6O4(OH)4 cuboctahedral units (MOF-525) or Zr6O8(H2O)8 unit (MOF-545). The synthesized MOFs were characterized by X-ray powder diffraction (XRD), N2 adsorption-desorption isotherm at 77 K, and scanning electron microscopy (SEM) measurements. The CO2 adsorption amount and BET surface area of both synthesized MOFs are up to 61.7 mg g-1 (MOF-525: 2325 m2 g-1) and 72.3 mg g-1 (MOF-545: 2040 m2 g-1) at 298 K/1 bar. Additionally, both porphyrin containing MOFs show excellent stability under aqueous and organic conditions. |
