ملخص المقال

A compound that has not been used before represented in powders consisting mainly of nickel oxide doped with 15%, 25%
and 50% zinc and manganese which was prepared from expired materials. To obtain these samples, Sol–gel method was
use. These powders were studied to identify their structural properties using X-ray rays (XRD) while the scanning electron
microscope (SEM) showed a spherical shape after addition. The results of infrared (IR) tests also showed the emergence of
the chemical bonds Ni–O, Mn–O and Zn–O appearing in the frequency range [400–750]cm−1.The optical properties showed
a noticeable increase in the optical absorbance when doping with Mn and Zn, especially in the visible region. On the other
hand, we were able to identify the extent of its effectiveness in the photocatalytic process by measuring the rate of decomposition,
as we obtained a total purification of all dyes in the orange II polluted solution using the compound 25% MZNO
within a period of time that did not exceed 25 min.
