Abstract
A metal-organic framework (MOF) includes cadmium, magnesium, linking units of 2,5-dihydroxyterephthalic acid complexed with cadmium and magnesium, and units of guanidine in an amount of 1 to 25 percent by weight (wt. %) based on the total weight of the MOF. The units of guanidine are reacted with the linking units of 2,5-dihydroxyterephthalic acid. The MOF is in the shape of spherical particles with a longest dimension of 50 to 250 nanometers (nm).
