Photodegradation of phenol over flame-made Sn-doped ZnO nanoparticles

Photodegradation of phenol over flame-made Sn-doped ZnO nanoparticles

Undoped ZnO and 0.5-5.0 at.% Sn-doped ZnO nanoparticles were synthesized by flame spray pyrolysis (FSP) using zinc naphthenate and tin (II) 2-ethylhexanoate dissolved in xylene as the precursors under a 5/5 (precursor/oxygen) flame condition. UV-Vis absorption characteristics of the samples were inv...
