Abstract

A new metal–organic framework (MOF) {[NH₂(CH₃)₂][Co₅(BTC)₃(OAC)₂ (DMA)₂]_n·1.25DMA·2.25H₂O} (1), has been synthesized and characterized. The thermal stability, optical properties and photocatalytic activity of 1 were also evaluated. Thermogravimetric analysis revealed stable thermal behaviour up to 172°C, while UV–visible spectroscopy indicated an optical band gap of 1.6 eV, suggesting semiconducting properties. Photocatalytic tests demonstrated efficient degradation of antibiotic pollutants under UV light, with optimal performance in degrading Ornidazole (ODZ) at 40 ppm and 5 mg/L photocatalyst dosage, achieving a degradation efficiency of 83.69%. Reusability tests showed stable photocatalytic performance over multiple cycles. Additionally, the photocatalytic activity of 1 was assessed in different water mediums, and its performance was affected by the presence of common inorganic anions, highlighting its potential for environmental remediation applications.

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
