University of Tehran Journal of Sciences, Islamic Republic of Iran 1016-1104 31 2 2020 04 01 Investigation of Catalytic Activity of Pillared-layer Ni (II) Metal-Organic Framework Derived NiO Nanoparticles for Aromatization of Hantzsch 1,4-Dihydropyridines 127 135 74787 10.22059/jsciences.2020.291546.1007461 EN Zeinab Asgharpour Alzahra University Faezeh Farzaneh Al Zahra University Journal Article 2019 11 13 The pillared-layer metal-organic framework of Ni<sub>2</sub>(BTEC)(bipy)<sub>3</sub>.3DMF.2H<sub>2</sub>O  (BTEC = 1,2,4,5-benzenetetracarboxylate; bipy = 4,4́-bipydine; DMF =N,Ń-dimethylformamide) was prepared, characterized and used as a precursor for preparation of NiO nanoparticles. The morphology and structure of NiO nanoparticles were characterized by XRD, SEM, FT-IR and EDX techniques.  It was found that the synthesized   MOF and NiO nanoparticles catalyze the aromatization of 4-substituted Hantzsch 1,4-dihydropyridines (R= Ph, Me, H) with 100% conversion and 100% selectivity toward the desired products.
