“…The photo-catalytic 16 technique supplies a good chance for us to degrade these chemicals 17 via a green route using the solar energy. Currently, the nano-oxide 18 semiconductor compounds are the most favorite as photo- 19 catalysts in air and water purification because of their nano-scale 20 sizes and subsequently higher photo-catalytic efficiency than bulk 21 ones, such as nano-TiO 2 , nano-ZnO, etc. [6][7][8][9][10].…”

“…These ZnO films not only exhibited surface 52 feature-dependent photo-catalytic activity, but also the facile 53 operability and separating characteristics were their outstanding 54 superiority. 55 Based on the understanding of the surface structure-function 56 relationship, we tried to recommend the opinion of "film-form 57 photo-catalysts with special surface features" in our series of work 58 [18,19] [20]. Typically, the electropolished aluminum sheet was set 74 as the anode and the kryptol acted as the cathode.…”

“…This might open the way to possible applications of such porous ZnO films as antireflective coatings and for graded-index multilayer systems. The anodic oxidation technique was also investigated [128]. Metallic Zn sheets were set as anodes in a three-electrode electrochemical cell apparatus, containing a 3% phosphoric acid in ethanol.…”

Zinc oxide (ZnO) thin films have been widely investigated due to their multifunctional properties, i.e., catalytic, semiconducting and optical. They have found practical use in a wide number of application fields. However, the presence of a compact micro/nanostructure has often limited the resulting material properties. Moreover, with the advent of low-dimensional ZnO nanostructures featuring unique physical and chemical properties, the interest in studying ZnO thin films diminished more and more. Therefore, the possibility to combine at the same time the advantages of thin-film based synthesis technologies together with a high surface area and a porous structure might represent a powerful solution to prepare ZnO thin films with unprecedented physical and chemical characteristics that may find use in novel application fields. Within this scope, this review offers an overview on the most successful synthesis methods that are able to produce ZnO thin films with both framework and textural porosities. Moreover, we discuss the related applications, mainly focused on photocatalytic degradation of dyes, gas sensor fabrication and photoanodes for dye-sensitized solar cells.

BACKGROUND Due to urbanization, the release of coloured wastewaters from textile industries into various environmental components has increased and is posing a threat to water bodies, so that their eradication from water bodies is necessary. To this end, semiconductor heterogeneous photocatalysis has emerged as a promising tool. However, as is well known, photocatalysis is a surface phenomenon; therefore it is strongly influenced by the fabrication technique employed for its synthesis. To address this issue, the present work demonstrates the dependence of synthetic methodology on photocatalytic efficacy of ZnO catalyst. RESULTS Catalytically active nanostructured ZnO particles were fabricated by five different facile methodologies. The fabricated nanostructures were critically analysed using techniques such as, X‐ray diffraction (XRD), high resolution transmission electron microscopy (HR‐TEM), Brunauer–Emmett–Teller (BET) and photoluminescence (PL) spectrophotometer. The photocatalytic activity of different ZnO catalysts was compared by using safranin O dye as probe molecule. CONCLUSIONS ZnO nanopowders fabricated by different methodologies were found to display different catalytic efficiencies, which was ascribed to large variations in specific surface area and rate of recombination of electrons and holes. Therefore, it is perceived that ZnO catalyst with best catalytic activity can be utilized to streamline the treatment of dye wastewater and is an ideal catalyst for a practical approach. © 2015 Society of Chemical Industry
