Effect of CdS distribution on the photocatalytic performance of resin - CdS nanocomposites / Yingmei Xie in Chemical engineering journal, Vol. 174 N° 1 (Octobre 2011) 

Public ISBD [article]  in Chemical engineering journal > Vol. 174 N° 1 (Octobre 2011) . - pp. 351–356 Titre : Effect of CdS distribution on the photocatalytic performance of resin - CdS nanocomposites Type de document : texte imprimé Auteurs : Yingmei Xie, Auteur ; Shujuan Zhang, Auteur ; Bingcai Pan, Auteur Année de publication : 2012 Article en page(s) : pp. 351–356 Note générale : Génie chimique Langues : Anglais (eng) Mots-clés : Shell  thickness  Shell  density  Rhodamin  B  D201-CdS Résumé : A nanocomposite, D201-CdS, made by depositing CdS nanoparticles on a resin support (D201) was found to be a promising photocatalyst with visible light response. To elucidate the structure-activity relationship, a set of D201-CdS nanocomposites varying in CdS amount and distribution were prepared by adjusting the concentration of sulfide anion and the precipitation time. The maximum compressive strength of the nanocomposites increased first with the loading of CdS and then declined with the further increase of CdS. There was a valid shell thickness of CdS due to the limitation of visible light in penetration through the resin matrix. Within a certain range of shell thickness, the increase of shell density of CdS would be favorable for the purpose of photodegradation. The shell density could be easily tuned by adjusting the fabrication condition employed in this work, which is an important merit for the potential production and application.
