Combustion synthesis of TiO2 nanoparticles as photocatalyst

Silane grafting of TiO2 nanoparticles: dispersibility and photoactivity in aqueous solutions

“…The anatase type is of great interest due to its chemical stability, non‐toxicity and photoactivation under ultraviolet (UV)‐beam irradiation 2. Among many types of semiconductor materials used for photocatalytic purposes, due to strong oxidizing power under UV irradiation, TiO 2 in anatase form has become the benchmark 3–5. The historical background of TiO 2 photocatalytic applications goes back to a series of reports published in 1956 6.…”

A comparative study of TiO2 nanoparticles synthesized in premixed and diffusion flames

“…Akurati [10] successfully obtained spherical, loosely agglomerated TiO 2 powders with a minimum secondary particle size of 90 nm and a maximum rutile content of 35 wt.% by applying low oxygen flow rates in the double diffusion flame. Kitamura [11] demonstrated that the shape and crystalline structure of TiO 2 particles was highly dependent upon the particle size of titanium precursors. For instance, rutile phases with an irregular shape were obtained from small titanium particles (average size (AS) of 10 μm), and anatase spheres were achieved when large particles were employed (AS of 25 μm).…”

Nano/Micro-Structured Materials: Synthesis, Morphology and Applications

“…The bottom-up method of nanoparticle synthesis involves nucleation of atoms followed by their growth in a self-assembly fashion to form the nanomaterial. Here we will look at the different nanostructured materials prepared by bottom-up methods such as hydrothermal, [8,9] combustion synthesis [10], gas-phase methods [11,12], microwave synthesis and sol-gel processing [13].…”
