“…Zinc oxide (ZnO), one of the most promising metal oxide semiconductors (MOS), which has a wide band gap of 3.37 eV with a high exciton binding energy of 60 meV [1], has found a wide range of applications, such as gas sensors [2][3][4], transparent electrodes [5], varistors [6] and etc. It has been proved that ZnO is a naturally n-type conductivity semiconductor caused by excess zinc [7].…”

“…Thus, the seeding layer should nucleate growth, giving variant grain growth characteristics compared to conventional APCVD thin films due to a reduced film growth induction time, by providing a lower activation energy barrier to improved film formation, yielding denser, faster growing and more adhesive films. 20,[46][47][48][49][50][51][52][53][54][55][56][57] The work presented in this paper explores FTO synthesis by the AA-AP CVD seed-overlay method. 45,46 Seeding strategies have been similarly used to good effect in the formation and control of microstructures in a variety of materials.…”

We report on the seeded growth of fluorine doped tin oxide (FTO) polycrystalline transparent conducting oxide (TCO) thin films on float glass using a novel two-step chemical vapour deposition (CVD) method. Aerosol-assisted CVD (AACVD) was used to grow a seed layer to direct and promote full film growth via an atmospheric pressure CVD (APCVD) overlay. The method allowed for reproducible control over morphology and denser, rougher, higher-performing TCO at a relatively low growth temperature (500 1C). Growth promotion depended on seeding time with an optimal seeding time being present, below which morphology control and conformal coverage was unavailable. The film properties and functional characteristics were characterised by SEM, AFM, XRD, XPS, UV-Vis-Near IR transmittancereflectance and Hall Effect probe measurements. Highly transparent and electrically conductive films, comparable to commercial materials and with high roughness and low transmission haze values indicate the process yields high quality films with a controllable morphology that can be tuned to desired application. The versatile method provides a route towards the morphological control of high-quality FTO thin films with high optical clarity and low-emissivity properties and can be readily extended to a variety of different substrates and metal oxide materials.

“…In order to overcome this shortcoming, nano-ZnO was loaded on some supporters (clay soil, glass marble, CNT yarn, activated carbon, metal screening, etc.) to avoid the separation and recover nanocatalyst [10][11][12]. Bentonite, as a carrier, has many advantages, such as low cost [10], great stabilization, big surface area, good adsorption performance, and high ion exchange [13].…”

Nano-ZnO supported on bentonite was prepared to form composite photocatalyst by sol-gel method. The photocatalyst was analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscope (TEM). C.I. Acid Red 35 was used as simulating contaminant to be treated by ultraviolet light synergistic with nano-ZnO/bentonite. The results show that 5.7 nm ZnO particle was acquired and uniformly dispersed on the surface of the bentonite at calcination temperature of 200°C. The removal of C.I. Acid Red 35 could reach 84.9% after 200 min under optimum ZnO/bentonite dosage of 0.6 g L−1. The 60% ZnO content in ZnO/bentonite composite exhibited a great photocatalytic activity to treat C.I. Acid Red 35. The photocatalytic process followed pseudo-first-order kinetics and the best apparent rate constant was 0.00927 min−1with correlation coefficient (R2) of above 0.98.
