“…There are many synthesis methods such as hydrothermal [18], microwave [19], supercritical antisolvent [20], and sol-gel [21] methods for preparation of TiO 2 nanoparticles. Hydrothermal, microwave, and supercritical antisolvents provided high purity and high surface equipment for TiO 2 synthesis, whereas the sol-gel method can be undertaken at atmospheric pressure and room temperature.…”

In this work, TiO2 nanoparticles were successfully synthesized with narrow size distribution via a wet ball milling sol-gel method. The effect of calcination temperature on photocatalytic activity was observed from particle size, crystallite size, and phase transition of TiO2 nanoparticles. Increasing calcination temperature increased particle size, crystallite size, and the crystallinity of synthesized TiO2. Phase transition depended on variation in calcination temperatures. A two-phase mixture of anatase and brookite was obtained with lower calcination temperature whereas a three-phase mixture appeared when calcination temperature was 500–600 °C. With higher temperature, the rutile phase kept increasing until it was the only phase observed at 800 °C. Anatase strongly affected the photocatalytic activity from 300 °C to 600 °C while the particle size of TiO2 was found to have a dominant effect on the photocatalytic activity between 600 °C and 700 °C. A mixture of three phases of TiO2-600 exhibited the highest methylene blue degradation with the rate constant of 9.46 × 10−2 h−1 under ultraviolet (UV) irradiation.

“…9 Photoreduction of CO 2 to liquid fuels is an attractive alternative that relies on photocatalysts such as zinc oxide (ZnO), 3,10 cadmium sulde (CdS), 2 and titanium dioxide (TiO 2 ). 5,6,[10][11][12][13][14][15][16][17][18][19] TiO 2 is a popular photocatalyst that has been used in the decomposition of organic pollutants in wastewater. It has also featured heavily as a potent photocatalyst for CO 2 conversion.…”

“…Whereas chemical composition, morphology and composition of phase can be optimized by pH, and temperature by employing hydrothermal and sol-gel techniques [33]. However, hydrothermal method works at a temperature above 200 o C which is very high and imparts influence on morphology of titania [34][35].…”

Titanium dioxide (TiO2) has been utilized for photovoltaic devices mostly as electron selective ply. Most of the transition metal complexes like TiO2 possess wider band gap to predominant relying on morphology of nano-particles. Most of the metal oxides possess excellent ability of harvesting extensive part of sunlight. This study reports, synthesis of TiO2 by using two different techniques i.e., sol-gel and hydrothermal. Later nano films was applied on fluorine doped tin oxide glass through spin coating at ambient temperature. Particles of TiO2 were synthesized at different temperatures however rest of the variable like solvent, concentration and amount of precursor were static. Nanoparticles of anatase titania synthesized through sol-gel had higher crystallinity. Particle size of synthesized particles was 12.2 nm at 25o C. Subsequently particles produced through hydrothermal procedure were large with an average particle size of 16 nm at 100o C. FTIR further confirmed the synthesis of anatase titania at 400-800 cm-1. X-ray diffraction technique also confirmed the synthesis of titania at 25.3o ,38.0o, 47o, 54.5o, 62.7o and 78o . UV-visible spectroscopy was performed to analyze optical properties exhibiting peak absorbance at 424 nm. This synthesized TiO2 anatase is extensively used for photovoltaic application.
