Bimetal NiCo-MOF-74 for highly selective NO capture from flue gas under ambient conditions

The mixed bimetal metal–organic framework Ni(0.37)Co(0.63)-MOF-74 has been constructed by the solvothermal method for NO adsorption. The results showed that bimetal Ni(0.37)Co(0.63)-MOF-74 takes up NO with a capacity of up to 174.3 cc g(−1) under ambient conditions, which is 16.3% higher than that o...

Sumario:The mixed bimetal metal–organic framework Ni(0.37)Co(0.63)-MOF-74 has been constructed by the solvothermal method for NO adsorption. The results showed that bimetal Ni(0.37)Co(0.63)-MOF-74 takes up NO with a capacity of up to 174.3 cc g(−1) under ambient conditions, which is 16.3% higher than that of the best single metal Co-MOF-74. The IAST adsorption selectivity for a NO/CO(2) binary mixture can reach a maximum of 710 at low adsorption partial pressure, while the regeneration performance can be retained even after five cyclic adsorption–desorption experiments. Its separation performance was further confirmed by breakthrough experiments, indicating this new bimetal Ni(0.37)Co(0.63)-MOF-74 as one of the best materials for NO adsorption and separation in flue gas.
