Abstract
In this paper, Ag–Ce–ZnO nanocomposites with average particle size of about 50 nm were prepared by direct precipitation method. In order to solve the problem of agglomeration, the nanocomposites with the average particle size of about 30 nm were obtained by treating the nanocomposites with surfactant sodium polyacrylate (PAAS). The effect of surfactant PAAS on the content of hydroxyl radicals produced by nanocomposites was determined by UV spectrophotometry and fluorescence spectrophotometry, and the effect of PAAS on the dispersion effect was obtained indirectly. The experimental results showed that the addition of surfactants’ PAAS effectively reduced the average particle size of nanocomposites, increased the content of hydroxyl radicals, and made the nanocomposites have good dispersing effect.
