Dioxo-molybdenum(VI) unsymmetrical Schiff base complex supported on CoFe2O4@SiO2 nanoparticles as a new magnetically recoverable nanocatalyst for selective epoxidation of alkenes

Nanomagnetic CoFe2O4@SiO2-EA-H3PO4 as a zwitterionic catalyst for the synthesis of bioactive pyrazolopyranopyrimidines and dihydropyrano[2,3-c]pyrazoles

“…1D). 25 The ndings validate that the CoFe 2 O 4 crystal structure remains unaltered even aer the addition of organic and inorganic layers onto its surface. Through the application of Debye-Scherrer's calculation, it has been established that the nanoparticles exhibit a dimension of approximately 17.43 nm, aligning closely with the ndings from TEM analysis.…”

Chemoselective Oxidation of Alkenes by Metal‐Organic Framework‐Supported Copper Catalyst

“…However, due to the poor selectivity, difficulty in separation and recycling of these homogeneous catalysts, it is a matter of the utmost urgency to develop highly active, selective, and reusable heterogeneous catalysts for economical and eco‐friendly oxidation of alkenes. Many heterogeneous catalysts, including metal oxides, [34–40] polyoxometalates (POMs), [41–44] and zeolites‐, silica‐ or carbon materials‐supported metal nanoparticles [45–65] have been developed for the oxidation of styrene. However, the poor selectivity of many of these catalysts in converting styrene to benzaldehyde impels further development of catalysts.…”
