Transition metal ions (Co and Cr) doped ZnO nanoparticles supported on natural zeolite were synthesized using co-precipitation method. The synthesized samples were characterized by means of X-ray diffraction, energy dispersive X-ray, Fourier-transform infrared absorption, and UV-visible diffuse reflectance spectroscopy. The samples were further used as photocatalyst for degradation of methyl orange and methylene blue in aqueous solutions under UV light irradiation. The results showed that zeolite supported Cr-doped ZnO nanoparticles is more efficient compared with zeolite supported Co-doped ZnO nanoparticles. It is also revealed that zeolite supported samples possessed higher photocatalytic efficiency compared to bare samples.

A series of metal element (Al, Fe, Mg and Ni)-doped ZnO (M-ZnO) photocatalysts have been successfully synthesized on graphene-coated polyethylene terephthalate (GPET) flexible substrate via the hydrothermal method. The effects of doped metals in ZnO were also studied on the crystal structure, morphology and photocatalytic performance. The photocatalytic experiment results indicated that, compared with Al-, Mg- and Fe-ZnO/GPET photocatalysts under ultraviolet (UV) light irradiation, Ni-ZnO/GPET had better photocatalytic activity, and the degradation rate of methylene blue (MB) was 81.17%. Meanwhile, the mechanism of enhancing the photocatalytic activity of metal element-doped ZnO is also discussed. It is concluded that, after doping with metal elements, electrons and holes are prevented from recombination by trapping electrons of the ZnO/GPET conductive band, thereby improving the photocatalytic activity.

Abstract In the present report, synthesis of pure, Nd-doped (1 wt.%) and Nd/Sm (1 wt.%) co-doped Zinc Oxide (ZnO) Nanoparticles (NPs) by using simple co-precipitation method. PXRD pattern of all the synthesized samples exposes the hexagonal crystal structure of ZnO NPs without any impurity. The various functional groups presented in the synthesized samples were analyzed by FT-IR studies. From UV-Vis DRS spectra, the band gap was found to be 2.81 eV, 2.90 and 3.10 eV respectively for pure, Nd-doped and Nd-Sm co-doped ZnO NPs. PL spectrum displays the broad emission at 393and 450 nm for all the synthesized samples. The agglomeration of flower-like morphology of pure ZnO NPs, flake-like structure of Nd-doped and rod-like morphology of Nd/Sm co-doped ZnO NPs were examined by SEM. Photocatalytic activity of the prepared samples for dye degradation of Acid Orange 7 (AO-7) and Acid Red 13 (AR-13) was studied under UV light. The result revealed that, the Nd/Sm co-doped ZnO NPs found to have efficient degradation candidate materials.
