Abstract
Aiming at purifying water at low cost for our daily life, the effect of different concentrations
MgO (10 wt% and 20 wt%) doped on ceramic-based ( mullite- cristobalite) and (mullite-
Zircon) powders, using to purifying water at low cost for our daily life. This powder has been
successfully prepared by traditional mixed method. The resulting structural and
morphological properties of the products were studied in order to determine the effectiveness
of their photocatalytic activities of Orange II under visible light. X-ray diffraction, Scanning
Electron Microscopy, energy-dispersive X-ray spectroscopy and UV-visible
spectrophotometry were used in this goal.
The results confirm that the higher the addition increases the granules size with DD3-type and
decreases with DD3Z-type. The morphology was found that the addition of 10 wt% MgO on
the ceramic (DD3+ZrO2) contributed to modify the morphology to approach the compact
flake-like structure and confirmed the doping of the basic elements Al, Si, Zr, Mg and O.
Photocatalysis is based on the creation of electron-hole (e-/h+) pairs resulting in the
generation of (•OH, •O-
2 ) radicals that degrade orange II.
In similar conditions, the MgO doped on the ceramics with addition of zirconia have shown
better performances than those without zirconia. The 10 wt % Mg content exhibited high
photocatalytic activity 77.33 % for only 5 min and the obtained maximum degradation rate of
Orange II is 92.95 % for an exposition time of 45 min with DD3Z/MgO powers.
Keywords: Ceramics/ MgO, Photocatalytic, Visible light, Degradation rate.
