Photocatalysts show great potential in environmental remediation and water splitting using either artificial or natural light. Titanium dioxide (TiO2)-based photocatalysts are studied most frequently because they are stable, non-toxic, readily available, and highly efficient. However, the relatively wide band gap of TiO2 significantly limits its use under visible light or solar light. We herein...

A TiO2 film photoanode with gradient structure in nanosheet/nanoparticle concentration on the fluorine-doped tin oxide glass from substrate to surface was prepared by a screen printing method. The as-prepared dye-sensitized solar cell (DSSC) based on the gradient film electrode exhibited an enhanced photoelectric conversion efficiency of 6.48%, exceeding that of a pure nanoparticle-based DSSC w...

A Ag/TiO2 nanocomposite, in which silver nanoparticles are highly dispersed in the uniformly sized pores of a cubic mesoporous TiO2 molecular-sieve film, has been fabricated.

TiO2 has been considered as a promising anode material for lithium ion batteries. However, its poor rate capability originating from the intrinsically low lithium ion diffusivity and its poor electronic conductivity hampers putting such an application into practice. Both issues can be addressed by nanostructure engineering and conductive surface coating. Herein, we report a template-assisted sy...

The metallorganic chemical vapor deposition method was successfully used to synthesize pure TiO2 and Nd3 -, Pd2 -, Pt4 -, and Fe3 -doped TiO2 nanoparticles. Polycrystalline TiO2 structure was verified with x-ray diffraction, which showed typical characteristic anatase reflections without any separate dopant-related peaks. Transmission electron microscopy observations confirmed the existence of ...

In this paper, we propose a simple procedure to obtain multi-walled carbon nanotubes (MWCNTs) decorated with TiO2–Ag nanoparticles (MWCNT–TiO2–Ag). The MWCNTs were via combined functionalization –OH and –COOH groups polymer-wrapping technique using poly(allylamine)hydrochloride (PAH). TiO2-modified Ag synthesized the Pechini method mixture of acetylacetonate-modified titanium (IV) isopropoxide ...

Boron-doped titanium dioxide (B-TiO2) films were deposited by atmospheric pressure chemical vapour deposition of titanium(iv) chloride, ethyl acetate and tri-isopropyl borate on steel and fluorine-doped-tin oxide substrates at 500, 550 and 600 °C, respectively. The films were characterised using powder X-ray diffraction (PXRD), which showed anatase phase TiO2 at lower deposition temperatures (5...

in this research, the thin films of n-s doped titanium dioxide (tio2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. furthermore, titanium dioxide (tio2) was functionalized with thiourea. furthermore, n-s doped titanium dioxides (nsto) were fixed on glass balls by glass balls fixed-bed reactor system. besides, the effect of ...

The development of new fabrication techniques of plasmonic nanocomposites with specific properties is an ongoing issue in the plasmonic and nanophotonics community. In this paper we report detailed investigations on the modifications of the microstructural and plasmonic properties of metal-titania nanocomposite films induced by swift heavy ions. Au-TiO2 and Ag-TiO2 nanocomposite thin films with...

Titanium dioxide (TiO2) incorporated ordered 2D hexagonal mesoporous silica (SiO2) films on a glass substrate were fabricated for use as a catalytic nanoreactor. Films were prepared using a tetraethyl orthosilicate (TEOS) derived SiO2 sol and a commercially available dispersion of TiO2 nanoparticles (NPs) in the presence of pluronic P123 as the structure directing agent. The effect of TiO2 dopi...
