This study investigated the feasibility of using Ag-TiO2 photocatalyst supported on glass fiber (Ag-TiO2/GF) prepared by a sol-gel method as an indoor air germicide. An experimental model was designed to investigate the bacterial disinfection efficiency of Staphylococcus (Staph), the most popular bacterium in hospitals in Korea, by the Ag-TiO2/GF photocatalyst. The silver content in Ag/TiO2 was...

A unique nanocomposite C-TiO2 was prepared by the growth of TiO2 on carbon nanoparticles using a simple hydrothermal procedure. Transmission electron microscopic (TEM) measurements showed that the nanocomposites exhibited an average core diameter of approximately 5 nm with a rather well-defined lattice space (0.4 nm) that was somewhat larger than that (0.38 nm) of the (100) crystalline planes o...

In2O3/nano TiO2 and In2O3/TiO2 (P-25) photocatalysts with different In2O3 loadings have been prepared by solid state dispersion method. These catalysts are characterized by XRD, surface area, TEM, UV-vis DRS and XPS techniques. XRD analysis shows the fine dispersion of In2O3 on the surface of TiO2. The photocombinates of In2O3 prepared using the lab-made TiO2 are nano sized with an average size...

Three-dimensional (3D) nanowire (NW) architectures are considered as superior electrode design for photovoltaic devices compared to NWs or nanoparticle systems in terms of improved large surface area and charge transport properties. In this paper, we report development of lead iodide perovskite solar cells based on a novel 3D TiO2 NW architectures. The 3D TiO2 nanostructure was synthesized via ...

The poly-o-phenylenediamine (PoPD)/TiO2 nanocomposite was successfully synthesized via 'in situ' oxidative polymerization method. The modified photocatalysts were characterized by BET, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier-transform infrarad spectra (FT-IR), thermogravimrtic analysis (TGA), X-ray photoelectron spectroscopy (...

Multilayer coating structure comprising a copper (Cu) layer sandwiched between titanium dioxide (TiO2) were demonstrated as a transparent heat reflecting (THR) coating on glass for energy-saving window application. The main highlight is the utilization of Cu, a low-cost material, in-lieu of silver which is widely used in current commercial heat reflecting coating on glass. Color tunable transpa...

In this paper, we have done the photodegradation of Methyl green dye in presence of prepared Ni0.10:La0.05:TiO2 nanocomposites. The nanocomposites of Ni0.10:La0.05:TiO2 was prepared by the solution impregnation method. The characterization of Synthesized TiO2 and Ni0.10:La0.05:TiO2 nanocomposites were done by X-Ray Diffractometer, SEM, TEM, UVVis, FT-IR, Band gap energy and BET. The photocataly...

Sandwich structured graphene modified TiO2 mesoporous single crystals (GR-MSCs) were obtained by using the graphene embedded silica spheres as the hard template, via a hydrothermal treatment. The selective photocatalysis of TiO2 can be achieved by controlling the location of graphene in TiO2 mesoporous single crystals. The sandwich structured graphene-TiO2 composite has a photooxidation surface...

In this study, the commercial TiO2 nanopowder and micropowder of anatase phase and rutile phase have been characterized by x-ray diffraction (XRD) and transmission electron microscopy (TEM). XRD patterns of nano-TiO2 in rutile and anatase phases exhibit broad peaks whereas both phases of micro-TiO2 demonstrate very sharp peaks. TEM images show that the grain size of TiO2 micropowders and TiO2 n...

The SrTiO3 modified rutile TiO2 composite nanofibers were synthesized by a simple electrospinning technique. The result of XRD, SEM and TEM indicate that the SrTiO3/TiO2 heterojuction has been prepared successfully. Compared with the TiO2 and SrTiO3, the photocatalytic activity of the SrTiO3/TiO2 (rutile) for the degradation of methyl orange exhibits an obvious enhancement under UV illumination...
