摘要

In this work, Ni-BDC MOF@Pr2O3 nanocomposite was prepared and characterized by various analytical techniques such as FT-IR, XRD, SEM, EDX and TGA. In FT-IR spectrum of Ni-BDC MOF@Pr2O3 composite, the transmittance peaks appeared at 601 cm− 1 and 452 cm− 1 correlated with Pr-O and Ni-O bonds, respectively. The diffraction peaks of composite (Ni-BDC MOF@Pr2O3) after incorporation of Pr2O3 were slightly shifted indicating fabrication of composite. The composite represents cauliflower like morphology. The elemental composition of prepared composite was assessed using EDX analysis. The thermal stability of composite was conducted using TGA analysis. The photocatalytic performance of the composite was investigated using methylene blue (MB) dye under a sunlight source with irradiation of 180 min. Maximum degradation exhibited 93.26% at pH = 12, which is higher than its precursors Ni-BDC MOF (83.90%) and Pr2O3 (78.65%). The antimicrobial activity was performed on Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa and Staphylococcus aureus, and maximum outcomes were shown for Escherichia coli and Bacillus subtilis with excellent zone of inhibition, respectively.
