Abstract: Mesoporous CeO2 nanospheres with appreciably high surface area are prepared using reversed micelles by a water-in-oil microemulsion method. The structural morphology and semiconducting properties of the nanoparticles are thoroughly investigated using X-ray diffraction, field effect… read more here.
