The Nature of PH3 decomposition reaction over amorphous CoNiBP alloy supported on carbon nanotubes / Lili Li in Industrial & engineering chemistry research, Vol. 49 N° 4 (Fevrier 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 4 (Fevrier 2010) . - pp 1658–1662 Titre : The Nature of PH3 decomposition reaction over amorphous CoNiBP alloy supported on carbon nanotubes Type de document : texte imprimé Auteurs : Lili Li, Auteur ; Han, Changxiu, Auteur ; Yang, Li, Auteur Année de publication : 2010 Article en page(s) : pp 1658–1662 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Carbon  nanotube  Amorphous  CoNiBP. Résumé : The carbon nanotubes (CNTs) supported amorphous CoNiBP catalyst is synthesized by means of induced electroless-plating method. The morphology, structure, and composition of the catalyst are characterized using a number of analytical instrumentations including transmission electron microscopy, X-ray diffraction, BET surface area measurement, and inductively coupled plasma. The activity of the catalyst in phosphine decomposition reaction is measured and correlated with its surface and structural properties. The characterization results show that the amorphous CoNiBP alloy nanoparticles, having average diameters of about 5−9 nm and 8−12 nm, are uniformly distributed inside and on the surface of CNTs, respectively. During phosphine decomposition reaction, some of phosphorus atoms migrate onto the CoNiBP particles, forming crystalline CoP phase which acts as the dominant active phase for phosphine decomposition reaction. Furthermore, the CoNiBP/CNTs catalyst exhibits high activity and stability in phosphine decomposition reaction. When operated in a fixed-bed reactor at 380 °C, single-pass phosphine conversion of about 99.7% can be achieved.
