Low temperature crystallisation of mesoporous TiO2.
Conducting mesoporous TiO2 is rapidly gaining importance for green energy applications. To optimise performance, its porosity and crystallinity must be carefully fine-tuned. To this end, we have performed a detailed study on the temperature dependence of TiO2 crystallisation in mesoporous films. Crystal nucleation and growth of initially amorphous TiO2 derived by hydrolytic sol-gel chemistry is...
متن کاملElectrospinning Synthesis and Photocatalytic Activity of Mesoporous TiO2 Nanofibers
Titanium dioxide (TiO(2)) nanofibers in the anatase structure were successfully prepared via electrospinning technique followed by calcination process. The morphologies, crystal structure, surface area, and the photocatalytic activity of resulting TiO(2) nanofibers were characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffracti...
متن کاملLow-Temperature Synthesis of Anatase TiO2 Nanoparticles with Tunable Surface Charges for Enhancing Photocatalytic Activity
In this work, the positively or negatively charged anatase TiO2 nanoparticles were synthesized via a low temperature precipitation-peptization process (LTPPP) in the presence of poly(ethyleneimine) (PEI) and poly(sodium4- styrenesulfonate) (PSS). X-ray diffraction (XRD) pattern and high-resolution transmission electron microscope (HRTEM) confirmed the anatase crystalline phase. The charges of t...
متن کاملLow-temperature synthesis of visible-light active fluorine/sulfur co-doped mesoporous TiO2 microspheres.
TiO2 nanomaterials with controlled morphologies have attracted extensive interest because of potential applications in solar energy conversion, environmental cleanup and hydrogen generation. Nanoscale titanium dioxides have been produced as nanotubes, nanosheets, nanowires and mesoporous microspheres by a variety of approaches. Among the various nanomaterials, mesoporous microspheres have drawn...
متن کاملUV/ozone-assisted low temperature preparation of mesoporous TiO2 with tunable phase composition and enhanced solar light photocatalytic activity
In this paper, we report a UV/ozone-assisted method for low temperature preparation of mesoporous TiO2 with controlled crystalline phase. The results showed that the crystallization of mesoporous TiO2 can occur at temperatures as low as 100 C under UV/ozone irradiation. Highly crystalline mesoporous anatase TiO2 was obtained after UV/ozone treatment at 200 C. The phase transformation from anata...
