An Effective Way For Promoting Photocatalytic Activity Of...

Abstract. An effective way for promoting photocatalytic activity of a semiconductor is doping of rare earth metal nanoparticles (NPs) onto it. Zinc oxide and Lanthanum doped Zinc oxide nanoparticles were synthesized by modifying the gel-combustion method. It was found that La can greatly enhance the cytotoxicity and photocatalytic activity of ZnO nanoparticles towards various cell lines and paracetamol drug. These nanoparticles were characterized by various spectroscopic and other techniques which clearly revealed the presence of lanthanum ions. The UV-vis spectroscopy displayed the absorption edge shifts towards the visible region after doping with La which is extremely favorable for absorbing the visible light. We compared the enhancing effect of La ions and found that La doped ZnO nanoparticles is more effective than ZnO nanoparticles in promoting the generation of hydroxyl radicals, holes and the photocatalytic activity of ZnO. Finally, the results of these studies provide a concise viewp oint in this important research area and specifically propose further research opportunities in optimizing the photocatalytic performance of La doped ZnO nanoparticles and widening the scope of their potential photocatalytic and biomedical applications.
