“…, which correspond to P-O stretching vibrations of the PO 4 3À group [24]. In the case of the pure CeO 2 , the FT-IR spectrum contains two characteristic absorption bands at 1583 and 1296 cm À1 , which are attributed to Ce-O bonds [25]. It can also be clearly seen that the FT-IR spectra of all CeO 2 /Ag 3 PO 4 composites are similar to that of the pure Ag 3 PO 4 , and the peaks do not shift (red shift or blue shift), which confirms that there is no covalent bond between CeO 2 and Ag 3 PO 4 nanoparticles.…”

The CeO 2 /Ag 3 PO 4 composite photocatalysts are synthesized by an in situ precipitation method. The XRD, FT-IR, XPS, TEM, EDS, and DRS are used to characterize the structure of the samples. The photocatalytic performance of the prepared samples is evaluated by the photocatalytic degradation of methylene blue (MB), rhodamine B (RhB), and ciprofloxacin (CIP). The results show that CeO 2 /Ag 3 PO 4 hybrid materials exhibit much higher photocatalytic activity than the Ag 3 PO 4 alone. The optimal CeO 2 content in CeO 2 /Ag 3 PO 4 composites is found to be molar ratio 1 wt%. Photocurrent response of CeO 2 /Ag 3 PO 4 (1 wt%) is about 1.5 times as high as that of the pure Ag 3 PO 4 . The increase of photocatalytic activity of CeO 2 /Ag 3 PO 4 composites could be mainly attributed to the heterojunction between CeO 2 and Ag 3 PO 4 . The trapping experiment has demonstrated that holes serve as the main active species for the degradation of MB under visible light irradiation. A photocatalytic mechanism is also proposed.

− A series of Ce-doped ZnO (Ce/ZnO) nanostructures were fabricated using the co-precipitation method, then a simply nontoxic hydrothermal approach was proposed for preparation of reduced graphene oxide (rGO)-Ce/ZnO composites. The synthesized composites were investigated by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), photoluminescence spectroscopy (PL), electrochemical impedance spectroscopy (EIS), UV-vis diffuse reflectance spectroscopy (DRS) techniques and Raman pattern. The as-synthesized rGO-Ce/ZnO composites showed high photodecomposition efficiency in comparison with the rGO-ZnO, Ce/ZnO, pure ZnO under UV, visible-light and sunlight irradiation. The degradation of methylene blue (MB) (10 mg/L, 100ml) by 95.8% within 60 min by using rGO-2 (10 mg) under sunlight irradiation was observed. The repeated use of the rGO-2 was investigated, and the results showed almost no decay in the catalytic activity.
