A simple wet-chemical synthesis method was developed to fabricate Zinc oxide micro-rod clusters. The synthesis process involved the rapid dilution of a zinc-bearing alkaline solution at 150°C in a convection oven on indium tin oxide (ITO) substrates. The synthesis was carried out by immersing an unseeded ITO substrate in a mixture of zinc nitrate hexahydrate (Zn(NO3)2·6H2O) and hexamethylenetetramine ((CH2)6N4) aqueous solution. The obtained sample was annealed at 400°C for 2 h. The structural, morphological and optical properties of the synthesized ZnO microstructures were investigated by X-ray diffraction, scanning electron microscopy and ultraviolet-visible spectroscopy, respectively. The ZnO rod clusters are hexagonal phase of the wurtzite structure. The crystal grain sizes of the films were found to be 72.6, 84.3 and 66.3 nm for the (100), (002) and (101) crystal planes, respectively. The optical bandgap of the ZnO was determined to be 3.147 eV.

“…Probably, ZnO is the second most studied photocatalyst. [801][802] ZnO also a wide bandgap semiconductor with similar conduction and valence band potentials as TiO2 and exhibiting a large active under UV light. One of the main problems is the stability of this metal oxide under even mild acid conditions.…”

Since their experiments, related semiconductors such as ZnO [203][204][205][206], SnO 2 [207][208][209][210][211], Fe 2 O 3 [212][213][214][215], and STO attracted a lot of interest as photoanodes and were studied extensively throughout the last decades. Among others, STO became one of the best investigated compounds and applications in the field of photocatalytic overall water splitting [216-225], applications for H 2 evolution [226][227][228][229][230][231][232][233][234][235][236][237], CO 2 conversion [238][239][240], inorganic/organic pollutant, NO x , SO x and dye degradation [233,[241][242][243][244][245][246][247][248][249][250][251][252][253][254], N 2 fixation [255], and bacteria ...…”
