Morphology dependent photocatalytic activity of ZnO nanostructures-A short review

“…The huge unique flower shapes surface area of associated with urchins improved photocatalytic activity in increased methylene blue absorption of and enhanced ZnO nanostructures photocatalytic activity flower like compared to the shapes of urchins. Meanwhile the photocatalytic response mesopores is an essential factor that can be administered [17].…”

Sensing properties of ZnO nanostructured layers

“…The temperature of the substrate was regulated with a control system, based on a Eurotherm equipment, including a steel heater with two pairs of thermoresistances and the respective reference thermocouples. From previous self-experience [10], we designed specific devices for characterizing the deposited layers. For this purpose, gold inter-digitated electrodes (10 µm of finger separation and 4×4 mm 2 of active area) were deposited onto 100 mm diameter SiO 2 /Si wafers.…”

One-step growth of isolated CdO nanoparticles on r-sapphire substrates by using the spray pyrolysis methodology

“…By using the SP technique, the growth of nanoparticles on the substrate can be regulated by controlling the growth parameters, solvent used to dissolve the solute/precursor etc. 31 Thus, by adjusting the growth parameters, a super-saturation condition can be achieved on the surface of the substrate that can lead to the growth of nanostructures over the substrate. Taking in mind the ability of the SP, aer the optimization of growth conditions, to grow NPs of different materials over various substrates 31,32 for the present work we did adopt the SP technique to study the growth of CdO NPs on r-sapphire substrates, in order to overcome the difficulties faced by the conventional growth techniques.…”

The choice of the substrate (r-sapphire) was made taking into account its technological interest and the previous study of our group on the growth of fully relaxed CdO thin layers on r-sapphire substrate using metal-organic vapour-phase epitaxy.…”
