AB  - The structural, microstructural, optical and photocatalytic properties of
hydrothermally obtained single-phase ZnO and CeO2@ZnO nanocomposites have
been investigated by the XRPD, FESEM, HRTEM/SAED and UV-vis techniques. In
order to improve the photocatalytic efficiency of ZnO, the optimal CeO2 content in
ZnO powders was determined by varying the quantity of CeO2 from 0 to 10 mol%.
The results showed that CeO2 with spherical crystallites of about 5 nm was
distributed onto the ZnO surface, whose crystallites displayed a bimodal
distribution, from nano- to microcrystallites. The morphology of ZnO particles
varied from elongated nanograins to microrods that further formed a 3-D tie-like
morphology which was disrupted by CeO2 adding. By degrading 90% of RO16 dye
in 180 minutes, the composite containing 5 mol% of CeO2 showed approximately
for 30% better photocatalytic efficiency comparing to other samples, although all the
obtained powders have similar structural, microstructural and optical characteristics.
This is obviously the optimal ratio of these two phases, in which synergy of CeO2
adsorption and ZnO photocatalytic effect reaches its maximum due to reduced
recombination rate and improved adsorption. The kinetic of RO16 degradation could
be described by a pseudo-first order model.
