Abstract

In this investigation, the Ce4+ doped ZnO nanoparticles (Zn/x%Ce) have been successfully synthesized via
simple ultrasonic assisted hydrothermal. The X–ray diffraction diagram showed that Ce4+ions has replaced
Zn2+ ions in the hexagonal structure of ZnO, forming nanoparticles. The hexagonal wurtzite lattice of ZnO is
not changed and the strain increased with the concentration of doped Ce4+. The FE–SEM and the TEM
images showed that Zn/x%Cenanoparticles had spherical aggregates with an average particle size of less
than 35 nm. Fourier transform infrared spectroscopy has demonstrated the Zn–O characteristic vibration
group and the material surface vibration groups. The BET parameters of the Zn/5%Ce material show that
the N2 adsorption/desorption isotherm is typical type III, with average capillary size and micropores. The
high purity and density distribution of elements Zn, O, Ce in the samples host, confirmed through X-ray
energy dispersive spectroscopy for elemental and mapping. Nanoparticles Zn/x%Ce will be applicability to
effectively removal for pollutants in environmental water.
