Synthesis and Optical Properties of Copper Terephthalate Metal Organic Frame Works

Abstract

Two new copper-based metal organic frame work (Cu-MOF21 and CU-MOF-22) was synthesized using bromo malonaldehyde and terephthalic an amino terephthalic acid. They synthesized CU-MOFs were characterized by FT-IR, UV-Visible spectroscopy. The XRD diffraction pattern indicated 2 θ at 17.3° and 26.8°. The Tauc’s method was employed to calculate the band gap of Cu-MOFs and was found that Cu-MOFS-21 exhibited 3.14 eV and Cu-MOF-22 with average bandgap energy at 3.61 eV attributed to the ligand-metal charge transfer. The results indicate that both Cu-MOFs can be further modified by suitable dopants to enhance the conductivity and reduce the band gap energy.

Controlling Multi-Drug-Resistant Traits of Salmonella Obtained from Retail Poultry Shops Using Metal–Organic Framework (MOF) as a Novel Technique

“…Concerning the incontrovertible bactericidal effect of Cu-MOF, Cu/Ni-MOF, and Cu/Ni/Co-MOF in control of Salmonella spp., it could be denoted by X-ray diffraction, which is primarily used to identify potential metal complex structures and additional structural evidence [62]. In Figure 2a for Cu-MOF (MOF 1), most of the peaks are consistent with the literature, which is matched with cards 89-2838 and 04-0836 for copper nanoparticles [63,64], and carbon is matched with JCPDS card no. 732058 [65,66].…”

“…Similar to alkene C=C str, N-H bending and O-H In the FT-IR spectrum of Cu-MOF (MOF 1) in Figure 3a, bands are observed at 3490 cm −1 and 3366 cm −1 , corresponding to O-H stretching and N-H stretching, respectively. The coordination link between the organic ligand and metal may be responsible for the lower frequencies of both bands [63]. Similar to alkene C=C str, N-H bending and O-H stretching frequencies are recorded at 1596 cm −1 , 1388 cm −1 , and 1111 cm −1 , respectively.…”

“…As shown in Figure 2c, the patterns of the Co-MOFs are attributed to the clear and distinct diffraction peaks at 2θ = 9.2 In the FT-IR spectrum of Cu-MOF (MOF 1) in Figure 3a, bands are observed at 3490 cm −1 and 3366 cm −1 , corresponding to O-H stretching and N-H stretching, respectively. The coordination link between the organic ligand and metal may be responsible for the lower frequencies of both bands [63].
