The data set include characterization data of a newly synthesized copper metal-organic framework (MOF), [Cu3(C9H3O6)2].3H2O{18H2O} and Benzene -1,3,5-tricarboxylic acid (H3BTC), as well as a UV visible absorption data for the photoactivity of [Cu3(C9H3O6)2].3H2O{18H2O} on the mineralization of Lissamine green SF (LGSF) and Tetraethylrhodamine (TeRh). The characterization data indicate tables and images and include Fourier transform infrared (FTIR) data, X-ray diffraction (XRD) data, Thermogravimetric analysis (TGA) data, Scanning electron microscope-energy dispersive X-ray (SEM-EDS) and Single Crystal XRD. The FTIR data identified functional groups such as OH, COO-, CH, C=C as well as Cu-O that confirm the formation of [Cu3(C9H3O6)2].3H2O{18H2O}. Clean peaks were observed by the XRD data for [Cu3(C9H3O6)2].3H2O{18H2O} which indicated that it was highly crystalline. The TGA data showed that [Cu3(C9H3O6)2].3H2O{18H2O} was thermally stable and could only be disintegrated at a temperature above 350oC. A cubic crystal octahedral morphology was identified for the SEM-EDS analysis . The single crystal data confirmed the cubic crystal geometry. The UV-visible adsorption data for TeRh and LGSF showed that the photocatalytic activity of [Cu3(C9H3O6)2].3H2O{18H2O} on LGSF and TeRh mineralization was found to be highly effective.


Steps to reproduce

The solvothermal synthetic technique was employed for the synthesis of [Cu3(C9H3O6)2].3H2O{18H2O}. The FTIR analysis was carried out using Bruker Alpha Spectrometer. About 1mg of the sample was carefully placed on the ATR crystal in the middle of the sampling surface. The anvil was pressed against the sample for suitable contact pressure against the ATR crystal to acquire a spectrum. The XRD analysis was executed using the Empyrean X-ray Diffractometer. The sample powder was packed tightly into the sample holder and scanned from 10o to 70o at 2 theta angle (2Ɵ) ` 48 geometry using Cu-Kα radiation at 45 kV 20 mA. The pattern obtained from the detector was analyzed using high score plus software to do a search match to identify sample peaks. The ZEISS EVO MA 15 Scanning Electron Microscope/Energy Dispersive Spectroscopy analyzer was used to determine the surface morphology and elements found in the Benzene-1, 3, 5-tricarboxylic acid and the [Cu3(C9H3O6)2].3H2O{18H2O}. Before imaging, the samples were sputter coated with gold/palladium alloy to provide a conduction path for the non-conductive samples to be imaged at high voltages (30kV). The samples were exposed to electron irradiation which resulted in X-ray emissions specific to the elements existing in the samples. The emitted energies were converted into spectral peaks of varying intensities identifying the different inorganic elements existing in the samples. For the single crystal XRD test, a small portion of [Cu3(C9H3O6)2].3H2O{18H2O} was suspended in NVH oil then aligned upon a Rigaku 007VHF diffractometer. The crystal was kept at a steady T = 100(2) K during data collection. The structure was solved with the ShelXT 2018/2 solution program using dual methods and by Olex2 1.5 as the graphical interface. The thermal stability of the [Cu3(C9H3O6)2].3H2O{18H2O} was examined using the SDT Q600 V20.9 System under a nitrogen atmosphere. A required amount of samples about 15 mg were loaded into an alumina pan and heated in a furnace programmed for a linear temperature change from room temperature to 800 °C at a heating rate of 5 °C/minute over some time. Nitrogen gas was utilized to create a uniform environment while the sample was being heated. A sample of [Cu3(C9H3O6)2].3H2O{18H2O} was added to LGSF and TeRh and stirred under solar radiation for 180 min to observe their mineralization by the [Cu3(C9H3O6)2].3H2O{18H2O}. UV- visible adsorption analysis was done using T70 UV/VIS Spectrometer and SHIMADZU GC-MS QP 2010 Plus was used to observe intermediate result from the mineralization test.
