This research focused on the preparation and characterization of Cu@N-TiO2/Ti (N-TiO2/Ti decorated with Cu) thin film electrode and its activities test in photoelectrocatalytic system. This study investigated the time effect of Copper (Cu) electrodeposition and the concentration of nitrogen (N) in the photocatalytic characteristics of TiO2. The catalyst has been prepared for activities test on ...

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 work, nanostructured TiO2 and Cr-doped TiO2 thin films were deposited on glass substrate through sonochemical-chemical vapor deposition (CVD) method. The resulting thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible absorption spectroscopy, and photoluminescence spectroscopy techniques. The TiO2 thin film has nanocubic morphology and ...

Due to the good photocatalytic activity, the TiO2@CNTs thin film is highly desirable to apply to the self-cleaning glass for green intelligent building. Here, the TiO2@CNTs thin film has been successfully achieved by polymer-assisted approach of an aqueous chemical solution method. The polymer, polyethylenimine, aims to combine the Ti4+ with CNTs for film formation of TiO2@CNTs. The resultant t...

Hydrophilic Cu-TiO2 thin films with a gradient in the Cu concentration were prepared on glass by layer-by-layer dip-coating from TiO2 precursors. The effects of the Cu doping on the structure and properties of TiO2 self-cleaning thin films are discussed. The Cu gradient markedly affects the hydrophilicity of the films, with the water contact angle significantly reduced compared with those of th...

The non-toxic and wide bandgap material TiO2 is explored as an n-type buffer layer on p-type Cu(In,Ga)Se2 (CIGS) absorber layer for thin film solar cells. The amorphous TiO2 thin film deposited by atomic layer deposition process at low temperatures shows conformal coverage on the CIGS absorber layer. Solar cells from non-vacuum deposited CIGS absorbers with TiO2 buffer layer result in a high sh...

copper sulphide (cu 2 s) thin films at different thicknesses and annealing temperatures were deposited onto glass substrate by vacuum evaporation method. xrd study reveals the phase transformation of cu     2 s film at higher thickness. optical and resistivity study show the phase transformation of the film from cu     2 s to cus when they are annealed at higher temperature. sem st...

We evaporated polycrystalline copper thin films of thickness between 10 and 100nm on silicon substrates with their native oxide under ultra-high-vacuum conditions. Some of them were exposed to air for a period ranging from 1 day to 2 weeks. X-ray photoelectron spectroscopy (XPS) revealed a clean copper surface with a trace of oxygen. These films that were exposed to air presented oxides in the ...

We tried to fabricate the Ge/TiO2 composite films with the differential pressure (pumping) co-sputtering (DPCS) apparatus in order to improve the optical properties. In the study, the micro structure of these thin films has been evaluated. TEM image revealed that the thin film was alternately layered with TiO2 and Ge, lattice fringes were observed both of Ge layer and TiO2 layer. There were por...
