3.1 Structural characterization. The IR spectrum (Fig 1) of the GO/MOFs showed strong absorption peaks at 1402 cm-1 and 1677 cm-1.The presence of an intense carbonyl peak at ca. 1710 cm-1 is attributed to the equivalency of the two carbonyl groups in the carboxylate-coordinated metal ion, in which electron clouds tend to be delocalized due to the conjugated π bond of π 3 5.
