Controlling Morphological Parameters of Anodized Titania Nanotubes for Optimized Solar Energy Applications
Anodized TiO2 nanotubes have received much attention for their use in solar energy applications including water oxidation cells and hybrid solar cells [dye-sensitized solar cells (DSSCs) and bulk heterojuntion solar cells (BHJs)]. High surface area allows for increased dye-adsorption and photon absorption. Titania nanotubes grown by anodization of titanium in fluoride-containing electrolytes ar...

متن کاملSpontaneous phase and morphology transformations of anodized titania nanotubes induced by water at room temperature.
We report a spontaneous phase transformation of titania nanotubes induced by water at room temperature, which enables the as-anodized amorphous nanotubes to be crystallized into anatase mesoporous nanowires without any other post-treatments. These mesoporous TiO(2) nanomaterials have a markedly improved surface area, about 5.5 times than that of the as-anodized TiO(2) nanotubes, resulting in a ...
متن کاملDynamic Diffraction Studies on the Crystallization, Phase Transformation, and Activation Energies in Anodized Titania Nanotubes
The influence of calcination time on the phase transformation and crystallization kinetics of anodized titania nanotube arrays was studied using in-situ isothermal and non-isothermal synchrotron radiation diffraction from room temperature to 900 °C. Anatase first crystallized at 400 °C, while rutile crystallized at 550 °C. Isothermal heating of the anodized titania nanotubes by an increase in t...
متن کاملAn Optimized Design of a Single Effect Absorption Solar Chiller for an Energy Consuming Optimized Designed Residential Building
Traditional fossil fuels lead to environmental problems and are also depleting. A significant portion of global energy consumption is due to building’s air conditioning. Nowadays there is a great attention toward renewable and sustainable energy sources to support the buildings energy requirements. In this study, a solar cooling machine was designed for a three-floor residential building under ...
