Synthesis, bioactivity and photocatalytic activity of citrate-stabilized ceria sols
Abstract
Cerium dioxide is a unique material which is promising for biomedical applications. The vast majority of currently existing methods of synthesis results in CeO 2 formation in the form of nanopowders. However such powders are useless as biomedical preparations because their exact dosage is nearly impossible. In this paper, we have offered a facile method of ceria stable sols synthesis and investigated the effect of varying concentrations and molar ratio of initial reagents on the CeO 2 particle size. The toxicity of ceria sols has been analyzed using Vibrio fischeri and Escheriсhia Coli bioluminescent microorganisms. Comparative studies of photocatalytic activity of ceria sols has been also performed
