Structural elucidation of N^O (ethylimino-methyl)phenol Fe(II) and Co(II) complexes and their applications in ethylene oligomerization catalysis

Structural and ethylene oligomerization studies of chelating (imino)phenol Fe(ii), Co(ii) and Ni(ii) complexes: an experimental and theoretical approach

“…For example, catalytic activity of 1608 kg mol −1 h −1 was obtained for the Ni1 complex, while its analogous complexes Fe1 and Co1 afforded catalytic activities of 918 kg mol −1 h −1 and 1036 kg mol −1 h −1 respectively (Table 2, entries 1–3), consistent with the literature findings. 23,56,57…”

Synthesis and Characterization of Trimetallic Fe-Co-V/Zeolite and Fe-Co-Mo/Zeolite Composite Nanostructures

“…In a typical preparation process for the fabrication of the Fe-Co-V/Zeolite sample, 3 mmol (0.54 gr) of vanadium pentoxide (V 2 O 5 ) was first dissolved into 1 mL of 1 M sodium hydroxide (NaOH) aqueous solution. The resultant yellowish product was then filtered to remove solid impurities and treated with adding nitric acid (HNO 3 ) (10 ml) to reach a solution containing V 10 O 28 6-. The obtained pinkish solution along with a 0.35 gr zeolite was placed into a flask equipped with a mechanical stirrer.…”

“…The obtained pinkish solution along with a 0.35 gr zeolite was placed into a flask equipped with a mechanical stirrer. The resulting mixture was heated at 60º C for 24 h to be completely absorbed V 10 O 28 6ions on the surface of the zeolite material. After that, iron (III) nitrate Fe(NO 3 ) 3 and cobalt (II) nitrate Co(NO 3 ) 2 solutions with the same molarity were added drop by drop into the above solution under continuous stirring at 60º C for 5 h. The final product was filtered, dried at room temperature, and calcined at 600º C for 5 h. The dried powder was finally treated in a reactor under pressure 20 bar at 500º C for 5 h.…”

“…Youn et al 5 described the morphological evolution of Fe-Mo bimetallic catalysts for the vertically aligned carbon nanotubes' diameter and density features modulation. The applications of N ^O (ethylimino-methyl) phenol Fe(II) and Co(II) complexes in ethylene oligomerization catalysis and their structural elucidation were studied by Ngcobo et al 6 . In artificial photosynthetic systems, hydrogen is generated with molecular catalysts of Co, Ni, Fe, and Mo 7 .…”

Ag2O/GO/TiO2 Composite Nanostructure: An Efficient Heterogeneous Catalyst for one Pot Synthesis of Bis (Dihydropyrimidinone) and Tetrahydro-4H-chromenes Derivatives

“…show advantages such as being inexpensive, non-toxic, and abundant in the earth [14]. The applications of N^O (ethylimino-methyl) phenol Fe(II) and Co(II) complexes in ethylene oligomerization catalysis and their structural elucidation were studied by Ngcobo et al [15]. In artificial photosynthetic systems, hydrogen is generated with molecular catalysts of Co, Ni, Fe, and Mo [16].…”
