Fabrication of multifunctional coating which combines low-e property and visible-light-responsive photocatalytic activity

Investigations on the Synthesis, Optical and Electrical Properties of TiO2 Thin Films by Chemical Bath Deposition (CBD) method

“…Such characteristics consist of high resistivity, heat reflecting windows, catalytic properties, photo thermal and photovoltaic 2 . Titanium dioxide (TiO 2 ) is an extensively used material for optical and protective applications because of its high transparency in the visible region, excellent mechanical durability and chemical stability in aqueous solution 3,4 . TiO 2 films are valuable for such applications as catalysis, optical coatings, gas sensors, and other electronic devices [5][6][7] .…”

Two-step nitridation of photocatalytic TiO2 films by low energy ion irradiation

“…The estimated etch rate of the ion gun was 0.044 nm/s for the TiO 2 thin-films. The photocatalytic property of each sample was evaluated by observing a photobleaching of methylene-blue (MB) solution, as described previously [7].…”

“…Moreover, much work has recently focused on the nitrogen-substituted TiO 2 (TiO 2Àx N x ) due to the possibility for improvement over TiO 2 in optical absorption and photo-reactivity under visible-light occupying the main part of solar radiation [2][3][4][5][6][7][8]. Based on firstprinciples calculations by Asahi et al, the substitutional N doping in the eight TiO 2 units, namely, the formation of TiO 1.875 N 0.125 , contributes to the modification of the electronic structure due to the mixing of N 2p with the valence band, leading to a decrease in the band gap energy [3].…”

“…In this method, H 2 + ions contribute to the effective substitution of N at the O sites because bombarded H 2 + ions cause a reduction of the TiO 2 not by preferential sputtering but due to chemical reactions [7]. Through X-ray photoemission spectroscopy (XPS) and reflection electron energy loss spectroscopy (REELS) analyses of the samples fabricated, we investigate the nitridation mechanisms under various ion-irradiating conditions.…”

Near Infrared Shielding Properties of Quaternary Tungsten Bronze Nanoparticle Na0.11Cs0.22WO3

“…A variety of thin film coating materials and technologies have been studied in academia and industry including rare-earth hexaborides, 2 indium tin oxides, 3,4 antimony-doped tin oxides, 5 and Low-E glasses. 6 However, ideal NIR absorbents are still in high demand due to the limitations of current technologies, such as low visible light transparency, 2 partial NIR shielding, 3,4 and high cost of material or processing.…”
