Abstract

Abstract : Under lower adsorption partial pressures and room temperature, the bimetallic Ni0.37 Co0.63 -MOF-74 shows much higher NO selective adsorption performance than all single metal M-MOF-74, providing bright promise for its NO capture from flue gas. Abstract : The mixed bimetal metal–organic framework Ni0.37 Co0.63 -MOF-74 has been constructed by the solvothermal method for NO adsorption. The results showed that bimetal Ni0.37 Co0.63 -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/CO2 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 Ni0.37 Co0.63 -MOF-74 as one of the best materials for NO adsorption and separation in flue gas.
