The pore structure of metal-organic frameworks (MOFs) is crucial to their adsorption performance, and it is still a challenge to precisely control the pore size to realize superior removal of uranium. The pore size of MOF-A, MOF-B and MOF-C was fine-tuned by using three organic chains with different lengths (fumaric acid, terephthalic acid and naphthalene dicarboxylic acid, respectively). The synthesized MOF-A, MOF-B and MOF-C had ordered increase in pore sizes with 3.8 & Aring;, 5.7 & Aring; and 7.6 & Aring;, respectively. Pore size of 7.6 & Aring; in MOF-C was a little larger than the geomet...
