In Situ Formation of Fe3O4/La2O3 Coating on the Surface of Carbonaceous Nonwoven to Improve Its Electromagnetic Wave Absorption Property

La(OH)3 nanoparticles immobilized on Fe3O4@chitosan composites as novel magnetic nanocatalysts for sonochemical oxidation of benzyl alcohol to benzaldehyde

“…04-0856). 17,18,23 The observed peaks show that the structure of Fe 3 O 4 and La(OH) 3 have not changed during the composition process.…”

“…Ultrasonic oxidation conditions play a key role in this process. Therefore, oxidation was done in the presence and absence of catalyst Fe 3 O 4 @CS/La(OH) 18). Finally, the catalyst with excellent results offers a very gentle and green option.…”

“…17 Among the rare earth oxides, lanthanum oxide has been considered as catalyst in various reactions due to its unique properties (good paramagnetic sensitivity, saturated magnetization, magnetostrictive properties, the large bandgap, etc.). 18 Therefore, lanthanum(III) oxide can be a good candidate for improvement of catalytic activity. 18,19 With this background, we designed, prepared and characterized Fe 3 O 4 @CS/La(OH) 3 nanocomposites as a novel heterogeneous catalyst for ultrasound-assisted oxidation reaction.…”

Some of the strange and unique attributes of applied oxidation protocol are short reaction time, great yield, green condition, simple recovery of nano catalysts, and easy workup.…”
