“…This fact is in agreement with the literature data which showed the high photocatalytic activity of nanocomposite Zn-Ce-O in other photocatalytic dye decomposition processes (Faisal et al, 2011;Li et al, 2011;Li et al, 2014;Saravanan et al, 2012).…”

The influence of mechanochemical treatment in air at different conditions (treatment time, ballto-powder ratio, diameter of the balls) on oxide zinc-cerium composition ZnO-CeO 2 ¼ 50:50 (molar ratio) properties was studied. The decrease in the particle size of oxides (CeO 2 -from 57 up to 18 nm, ZnO -from 174 up to 40 nm) and formation of Zn-Ce-O nanocomposite was shown by X-ray diffraction and transmission electron microscopy methods. The optimal treatment conditions (diameter of the balls 5-10 mm, ball-to-powder ratio ¼ 15, time treatment 2-4 hours) were established. An increase in the specific surface area (up to three times) and pores volume due to the formation of mesopores with two dimensions (2.1 and 30 nm) at these conditions was shown by Brunauer-Emmett-Teller (BET) and Barrett-JoynerHalenda (BJH) methods. The increase in the photocatalytic activity of the dye safranin T decomposition due to the formation of Zn-Ce-O nanocomposite was established.

“…For the coupled metal oxide, Zn 2 Ce (Fig. 9c), the peak in the range of 440e573 cm À1 is due the combined absorption ZneO and CeeO bonds [15,16]. The broad absorption around 3430 cm À1 shown by all the three is assigned to the stretching vibration of adsorbed water, since the nanocrystalline materials exhibit a high surface to volume ratio and thus absorb moisture.…”

“…Different chemical methods are used for the synthesis of ZnO/ CeO 2 composites, such as electro deposition [14], electro spinning [15], chemical vapor deposition [18], hydrothermal synthesis [19], soft solution chemical route [20], the solid-stabilized emulsion route [21], sol-gel method [22] and the precipitation technique [23]. We have used microwave assisted solution combustion synthesis for the preparation of individual and coupled ZnOeCeO 2 nanometal oxides.…”

Abstract. CeO 2 /ZnO composite nanoparticles are synthesized by using in-situ precipitation method, without any stabilizers, via conventional i.e. non-ultrasound (NUS) and ultrasound-assisted processing technique (US). The structure, morphology, particle size and % weight loss of the synthesized nanoparticles were analyzed by using X-ray powder diffraction (XRD), Thermogravimetric Analysis (TGA), Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) to establish the formation of core shell type nanomaterials with an average particle size under 15 nm. The effectiveness of the synthesized core shell morphology of CeO 2 /ZnO (catalyst) for the photocatalytic degradation of Rhodamine B (RhB) dye has also been investigated. It has been observed that the catalysts prepared by sonochemical method exhibit higher photocatalytic activity as compared to the catalysts prepared by the conventional method. It was also found that the ultrasound-assisted technique is an energy efficient method as it saves more than 80% of energy along with a substantial reduction in reaction time, as compared to conventional synthesis technique.
