sonochemistry; ZnS-coated TiO2 nanoparticles
TiO2 nanoparticles were easily coated with ZnS in nano-scale through a simple one pot reaction under multibubble sonoluminescence (MBSL) conditions which can provide a very powerful and efficient coating system. The coating depths of ZnS shell were in 2-5 nm range in a core/shell type nanostructure which is very likely to be useful for the development of inorganic dye-sensitized solar cells. The ZnS-coating depths on TiO2 in this system were found to be easily controlled in nano-scale by aqjusting the amount of reactants and/or the sonication time. The ZnS-coated TiO2 nanoparticles were characterized by XRD, UV-vis, EDS, and HR-TEM. (C) 2007 Elsevier B.V. All rights reserved.
