Pd on Amine-Terminated Ferrite Nanoparticles:  A Complete Magnetically Recoverable Facile Catalyst for Hydrogenation Reactions

Abstract

[structure: see text]. The present communication reports a facile route for Pd(0) immobilization on the surface of amine-terminated Fe3O4 and NiFe2O4 nanoparticles for a series of hydrogenation reactions. The catalysts are completely recoverable with the simple application of an external magnetic field, and the efficiency of the catalyst remains unaltered even after 10 repeated cycles for each of the reactions.

Fe3O4@mesoporouspolyaniline: A Highly Efficient and Magnetically Separable Catalyst for Cross‐Coupling of Aryl Chlorides and Phenols

“…[11] Especially, superparamagnetic microspheres coated with various polymers, biopolymers and inorganic materials have unique importance due to their magnetic separation properties. [12] In this context recently Deng et al and Leung et al have reported the preparation of polyaniline (PANI)/Fe 3 O 4 . [13,14] Though the applica-tions of Fe 3 O 4 magnetic particles have been explored in several areas, their usage in catalysis is largely exploited for immobilization and support.…”

Fabrication of palladium nanoparticles immobilized on an amine-functionalized ceramic membrane support using a nanoparticulate colloidal impregnation method with enhanced catalytic properties

“…Apart from the surface properties, the preparation method is another key factor affecting the amounts and quality of deposited metal nanoparticles. A number of methods are available to incorporate metal nanoparticles into porous supports, with impregnation of the support by noble metal anions and subsequent reduction being the most common [11][12][13]. The method usually yields metal nanoparticles of non-uniform size and shape, and the degree of catalyst dispersion depends on various factors such as the type of support, the deposition pH and the concentration of precursors in the solutions.…”

Anthranilic acids from isatin: an efficient, versatile and environmentally friendly method

“…A few methods are available for the synthesis of unsubstituted anthranilic acid. Although yields are high, the reaction conditions are often severe GABRIEL F. RIO, BÁRBARA V. SILVA, SABRINA T. MARTINEZ and ANGELO C. PINTO and/or require the use of expensive reagents which need careful handling (Xu and Wolf 2009, Guin et al 2007, Pandarus et al 2011.…”
