Modulation of Optical Band Gap of 2-Amino Terephthalic Acid Cu-MOFs Doped with Ag<sub>2</sub>O and rGO

The synthesized MOF with copper metal dopant has shown band gap around 1.5 eV which falls in the UV region of electromagnetic spectrum. This MOF with copper turns into nano/MOF composite with addition of Ag 2 O and rGO to it. The results of band gap of MOF/ Ag 2 O and MOF/rGO showed 1.904 eV and 1.639 eV respectively. This shift in band gap supports to use them as a UV and near visible light harvest catalyst and also assist in enhancing mechanical, thermal and structural behaviour of compounds. The enhancement of band gap of MOF/nanoMO is attributed to the quantum size effect.
