Abstract

   Ce and Mn-doped ZnO nano-oxides synthesized by gel combustion method at a temperature of 5000C from polivinyl alcohol (PVA) and salts Zn(NO3)2, (NH4)2Ce(NO3)6 or Mn(NO3)2. Phase composition and morphology of the material was determined by X-Ray  diffraction, and Transmittance Electron Microscopy (TEM). The results showed that, at 5000C were obtained single-phase oxides, particles evenly distributed. In which the diameter of Ce-doped ZnO oxide and Mn-doped ZnO oxide ≤ 40nm. To study the effect of time, volume, temperature levels and the ability to catalyze the decomposition of phenol red. UV light, showed P = 11W on nanoscale oxides are capable of color losing phenol red with over 80% efficiency. Keywords: Ce and Mn-doped ZnO nano-oxides, combustions, photocatalytic, PVA.
