Influence of Nano Particles on Optical Properties of Cu-MOFs

Abstract:

A copper metal organic frame work (MOF) is synthesized by taking adequate concentration of 2-mercaptobenzothiazole, 2-bromomalonaldehyde, 1,4 dicarboxylic acid and copper nitrate. Cu-MOF /Ag₂O and Cu-MOF/rGO composites are fabricated and is characterized by XRD, UV-Vis spectroscopy and FT-IR. The band gap of the MOF/ nanocomposites is reduced when compare to individuals so that a good visible light harvesting catalyst is formed. This reduction of band gap is due to the either create of shallow state with small ionization energy, very close to the valence and conduction band edge. KEYWORDS: Mercaptobenzothiazole, 2-bromomalonaldehyde MOFs, Copper Composites, Optical Properties, Ag₂O, rGO.
