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 ...

Herein, we have successfully prepared self-doped carbon dots with nitrogen elements (NCD) in a simple one-pot hydrothermal carbonization method, using L-histidine as new precursor. The effect of as-prepared was studied for photoelectrochemical (PEC) water splitting by decorating NCDs upon TiO2 nanorods systematically changing the loading time from 2 h to 8 (TiO2@NCD2h, TiO2@NCD4h, TiO2@NCD6h, a...

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 ...

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...
