Nanocrystalline TiO2 polymorphs with nonstoichiometry, i.e. having intrinsic and/or impurity structural defects, attract considerable interest due to enhanced optical and catalytic activity, improved electronic properties, existence of room-temperature ferromagnetism. Herein, combination hydrothermal technology, ion exchange process, high-temperature vacuum annealing, a gray-colored bronze tita...

We herein propose a proof of concept full dual-band electrochromic (EC) device able to selectively modulate solar light between 300 and 1600 nm. Dual-band control was achieved by exploiting the complementarity cooperation two earth-abundant nontoxic transition metal oxide nanocrystalline materials absorb different spectral regions when electrochemically charged. The active were obtained through...

In the present study we have investigated dielectric properties such as constant (ε'), loss (ε"), real part of electrical modulus (M'), imaginary electric (M") and AC conductivity, (σac) in wide range applied voltage, temperature frequency for Ni/n-TiO2/p-Si/Al heterojunction. A nanocrystalline TiO2 layer was grown on p-type boron doped silicon oxygen-controlled environment using optimized KrF ...

Investigation into integrated PEC/PVC for water splitting and light harvesting has focused on doping, QD sensitization and nanomaterials morphology. We have demonstrated, for the first time, PVC based on combined use of nitrogen doping and CdSe QD sensitization of nanocrystalline TiO2 thin films with promising results for solar energy conversion. Such TiO2:N/CdSe PVC produced an incident-photon...

The objective of this research was to investigate how the photocatalytic activity pure TiO2 can be improved by SnO2 modification. Different molar ratios tin titanium were prepared. correlation between concentration and structural properties investigated explain mechanism efficiency optimize synthesis conditions obtain enhanced SnO2-modified photocatalysts under UV-irradiation. prepared a low-te...
