Abstract ZnO nanomaterials with the stereochemical structure were becoming a research focus in the scope of photocatalytic materials, but the ZnO was sensitive to UV light rather than the solar light source, which considerably prohibited its extended application. ZnO nanomaterials coupled with other nanomaterials could generate the alternative composite heterojunction nanomaterials to promote the photocatalytic activity. Herein, we reported two facile and feasible synthesis methods to fabricate TiO2/ZnO cube nanocomposites and Ag/ZnO hollow spheres by hydrothermal reaction and chemical deposit

Abstract:
Ag-based low-E films with a multilayer construction of top-Si3N4/SnO2/NiCrOx/Ag/ZnO/ NiCrOx/TiO2/under-SiOxNy were deposited on unheated glass by vacuum magnetron sputtering and then post-treated in the glass tempering furnace at 675±25°C for 4 min, 5 min and 6 min, respectively. The effects of tempering time on the surface morphology, optical and micro-mechanical properties have been investigated. The results show that the edge of the particles become vague with the increasing time. After tempering, the transmittance of 550 nm is higher than that of the as-deposited glass of 75.89%. Ag-based

Composite films based on catalytically active forms of titanium dioxide synthesized on the fibrous structure of glass fabric are a promising solution for the creation of antibacterial filters for photocatalytic oxidation of microorganism cells under the influence of light radiation of the visible region of the spectrum. The filter obtained in the present work is a multilayer TiO2-SiO2-Ag composite film bonded to fibres of glass fibre carrier. This material has photocatalytic activity due to the presence of titanium dioxide in the anatase phase, which under the influence of light radiation is a
