Supported TiO2 films deposited at different energies: Implications of the surface compactness on the catalytic kinetics

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines, Stefanos Giannakis

Insight is provided in this study for the effect of the TiO2film densification/compactness on polyethy-lene (PE-TiO2) by sputtering TiO2at two very different energy levels. Uniform, adhesive low energy filmswere prepared by direct current magnetron sputter ...

Insight on the photocatalytic bacterial inactivation by co-sputtered TiO2-Cu in aerobic and anaerobic conditions

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines, Stefanos Giannakis

Co-sputtered TiO2-Cu polyester (TiO2-Cu-PES) under actinic light induced bacterial reduction of E. coli in the presence of O2 (air) and under anaerobic conditions. The bacterial inactivation/oxidation proceeds in the absence of O2 (air) probably due to the ...

Kinetics and mechanism for transparent polyethylene-TiO2 films mediated self-cleaning leading to MB dye discoloration under sunlight irradiation

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

Polyethylene-TiO2 (from now on PE-TiO2) transparent, non-scattering sputtered films have been found effective in the discoloration of methylene blue (MB) under low intensity solar simulated light. By Fourier transform attenuated infrared spectroscopy (ATR- ...

Temperature-dependent multiangle FTIR NIR-MIR ellipsometry of thermochromic VO2 and V1-xWxO2 films

Rosendo Sanjines, Andreas Schueler, Antonio Paone

VO2 and W-doped VO2 thin films were prepared by Radio Frequency (RF) reactive magnetron sputtering using V-metal target. The amount of W doping was quantified by Rutherford Backscattering Spectrometry (RBS). The optical constants of VO2 and V1-xWxO2 films ...

Preparation and Mechanism of Cu-Decorated TiO2-ZrO2 Films Showing Accelerated Bacterial Inactivation

César Pulgarin, Rosendo Sanjines, Juan Kiwi, Sami Rtimi

Antibacterial robust, uniform TiO2-ZrO2 films on polyester (PES) under low intensity sunlight irradiation made up by equal amounts of TiO2 and ZrO2 exhibited a much higher bacterial inactivation kinetics compared to pure TiO2 or ZrO2. The TiO2-ZrO2 matrix ...

Innovative photocatalyst (FeOx–TiO2): transients induced by femtosecond laser pulse leading to bacterial inactivation under visible light

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines

This study reports the photosensitizing effect/mechanism of FeOx under visible light irradiation and charge transfer to TiO2 on FeOx–TiO2 cosputtered film. The transients which were photo-induced by femtosecond laser pulses at 545 nm (25 fs) were identifie ...

Novel FeOx–polyethylene transparent films: synthesis and mechanism of surface regeneration

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

The first evidence for the synthesis of a uniform, adhesive polyethylene–FeOx (PE–FeOx) surface leading efficiently to bacterial inactivation is addressed in this study. PE was loaded with 0.04–0.08% Fe wt/wt PE after RF-plasma pretreatment was required to ...

Influence of doping in thermochromic V1−xWxO2 and V1−xAlxO2 thin films: Twice improved doping efficiency in V1−xWxO2

Jean-Louis Scartezzini, Andreas Schueler, Rosendo Sanjines, Antonio Paone

The parameters of thermal evaporation and magnetron sputtering deposition were optimized for fabrication of vanadium dioxide thin films. The O2 partial pressure during film deposition is critical for obtaining a pure VO2 phase. Thermochromic V1−xWxO2 (x = ...
