Degradation of ۴-Nitrophenol (۴-NP) Us ing Novel Composites as Zn O Nanoparticles Supporte d on Zeol ites

Until now, various methods have been em ployed to prepare ZnO nanoparticl es with extr emely small diameters including pr ecipitation of colloids in solution [۱], thermal decomposition methods [۲], pulsed laser deposition (P LD) [۳]. In general it is very difficult to avoid the aggre gation of ZnO nanoparticles during the prepa ration. This work aims to resolv e this problem via the growth of Zn O nanoparticles inside the channels of a poro us matrix su ch as zeolit e. Zeolites are crystalline nano porous materials possessing intercon nected Cha nnels those are accessible to molecu les of suitab le size.
