“…In this connection, ZnO is considered as one of the most important nanostructured materials 1 in nanotechnology because of its structure richness and novel properties. To date, various morphologies of ZnO have been synthesized such as nanobelts, 2 nanocombs, 3 nanosheets, 4 nanocages, 5 nanorings, 6 needle-like nanowhiskers, 7 nanorods 8,9 and nanoforest. 10 These morphologies have variety of practical applications which motivated the researchers towards controllable synthesis of ZnO nano-architectures.…”

Facile and low-cost aqueous chemical bath deposition route has been demonstrated to fabricate Eu-and Sm-doped ZnO microstructures. The effect of Eu and Sm ions on the morphology of the ZnO was investigated. The synthesized doped ZnO microstructures were systematically characterized by field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman and Fourier transform infrared spectra. FESEM images depicted the formation of Eu-doped ZnO microsphere and Sm-doped ZnO microplates. XRD spectra showed single crystalline nature of the undoped ZnO microdisks, whereas Eu-and Sm-doped ZnO exhibited the polycrystalline nature. The presence of Eu and Sm ions in the ZnO matrix was confirmed by XPS. This means that all the Eu ions substituted Zn 2+ as Eu 2+ into the ZnO matrix, whereas most of Sm ions were being in the trivalent state. This was probably due to the segregation of Sm 2 O 3 species on the surface of ZnO microstructures.

“…The various vibrational bands arised for CdS structure i.e. one broad peak in the region of 3300e3600 cm À1 centered at 3419.99 cm À1 and one weak peak at around 1628.62 cm À1 was due to stretching and bending vibration of OeH group respectively [19,23]. Peaks appeared at 2854.25 and 2924.24 cm À1 corresponds to CeH stretch vibration.…”

“…All PEC studies were carried out in 0?5M Na 2 SO 4 (pH 6?8) solution, which served as supporting electrolyte medium. The ZnO/Zn electrode was scanned from 2500 to 1500 mV(Ag/AgCl) at a rate of 5 mV s 21 . Amperometric I-t curves were performed by measuring the current as a function of the time at z0?50 V(Ag/ AgCl).…”

“…16 ZnO nanorods, nanowires and nanobelts have extensive application potential in nanogenerators, piezoelectric field effect transistors and chemical sensors, piezoelectric diodes, triggers, transducer and actuator, and flexible piezotronic strain sensors. [17][18][19][20][21] In recent years, there have been many reports on the preparation of ZnO nanorods by thermal evaporation, alumina templates, chemical vapour deposition and electrochemical deposition. [22][23][24][25] However, these preparation methods still involve some complex procedures, sophisticated equipment and rigorous experimental conditions.…”

A photoanode based on ZnO nanorod array film has been successfully synthesised on zinc foil by a simple approach in the NaOH aqueous solution, without the assistance of any catalyst, templates or high temperature and its implementation as photoanode in photoelectrochemical cells for hydrogen generation from water splitting was studied. In this approach, zinc foil was used not only as a substrate but also as a zinc ion source for the direct growth of ZnO nanorod arrays. ZnO nanorod array films were characterised by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The resulting ZnO nanorod showed a diameter of about 70-90 nm and the average length is estimated to be in the range of 0?5-2?0 mm. The good photoresponse of this ZnO nanorod array films have wide applications in the photoelectrochemical field. Therefore, these results suggest substantial potential of ZnO nanorod films in photoelectrochemical water splitting applications.
