Phase composition, crystal structure and microstructure of silver and tungsten doped TiO2 nanopowders with tuneable photochromic behaviour

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

“…It is also an excellent electrode material that can be used for the conversion of light energy into electrical energy because of its semiconductor properties. Its wide applications such as supercapacitors, dye-sensitized solar cells, quantum-dot-sensitized solar cells, lithium ion batteries, photoelectrolysis, water splitting, biosensors, photochromic devices, self-cleaning, and extremely thin absorber (ETA) solar cells have already been explored [8][9][10][11][12][13][14][15][16][17] . TiO 2 films can be synthesized by many chemical and physical deposition techniques, such as chemical vapor deposition, spin coating or spin casting, atomic layer deposition, molecular beam epitaxy, sputtering, cathodic arc deposition, electrospray deposition, sol-gel process 18 .…”

One-step Synthesis of Ag3PO4/Ag Photocatalyst with Visible-light Photocatalytic Activity

“…A series of new hybrid photocatalysts on the basis of surface plasmon resonance (SPR) of metal nanoparticles 4,5 , namely, plasmonic photocatalysts 6 , were developed to decompose various organic pollutants under visible-light irradiation. Tobaldi et al 7,8 have reported that the incorporation of Ag NPs can significantly improve the photocatalytic activity of TiO 2 nanopowders. Chen et al 9 also revealed that the SPR effect of Au nanoparticles could induce visible-light-driven photocatalytic activity of Au/ZrO 2 and Au/SiO 2 photocatalyst.…”

Plasma sprayed rutile titania-nanosilver antibacterial coatings

“…The low concentration of AgNPs could minimize the potential cytotoxicity of silver as well as reducing costs. Moreover, TiO 2 /Ag coatings were fabricated on stainless steel substrates by a simple and economical method that can be readily adopted industrially [4,6,12]. There was no phase change in the rutile of titania in the plasma spray process (Fig.…”

“…The structure of rutile (tetragonal, space group P4 2 /mnm) is made of chains of TiO 6 octahedra that share a vertex along the c-axis, and rutile is the most thermodynamically stable phase of the three polymorphs [6]. Moreover, rutile is known as an anti-wear and anti-corrosion material with excellent mechanical properties [7,8].…”

“…Among these techniques, APS is a particularly appropriate technique because a large area of TiO 2 can be easily deposited without any special requirements, such as vacuum pressures or reactive atmospheres [6].…”
