Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 15 (Avril 2012) . - pp. 5608-5614 Titre : Recoverable platinum nanocatalysts immobilized on magnetic spherical polyelectrolyte brushes Type de document : texte imprimé Auteurs : Shuang Wu, Auteur ; Julian Kaiser, Auteur ; Xuhong Guo, Auteur Année de publication : 2012 Article en page(s) : pp. 5608-5614 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Polyelectrolyte Résumé : Recoverable platinum nanocatalysts immobilized on magnetic spherical polyelectrolyte brushes (MSPB) were synthesized and characterized by high resolution transmission electron microscope (HRTEM), thermal gravimetric analysis (TGA), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). High catalytic activity was found by photometrically monitoring the reduction of 4-nitrophenol by NaBH4 in the presence of MSPB-Pt composites. An excellent stability and recyclability of catalyst was observed after consecutive eight runs following by external magnetic-separation and redispersion. This novel approach provides an excited potential application in preparation of recyclable metal nanocatalysts with high activity.
