Effect of reaction time on the particle size of ZnO and ZnO : Ce obtained by a sol-gel method
(Springer, 2004-01-01)
In this work particles of ZnO of size range 33-56 Angstrom were prepared by a sol-gel method. The effect of reaction time on the particle size of ZnO or ZnO:Ce was investigated by transmission electron microscopy measurements, ...
Structural study of copper oxide supported on a ceria-modified titania catalyst system
(Kluwer Academic/plenum Publ, 2002-01-01)
A structural study of CuO supported on a CeO2-TiO2 system was undertaken using X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS) techniques. The results of XRD revealed the presence of only two phases, TiO2 ...
