ZnSnO ternary metal oxide for ultraviolet radiation filter application: a comparative study with TiO and ZnO.

Ultraviolet (UV) radiation causes serious health risks. Inorganic metal oxides, such as titanium dioxide (TiO) and zinc oxide (ZnO), have long been recognized for their effectiveness as UV radiation filters/blockers in sunscreen formulations. TiO and ZnO as UV-blocking materials have some limitations and issues such as producing harmful radicals and toxicity, respectively.

Solvothermally Synthesized Hierarchical Aggregates of Anatase TiO Nanoribbons/Nanosheets and Their Photocatalytic-Photocurrent Activities.

Hierarchical aggregates of anatase TiO nanoribbons/nanosheets (TiO-NR) and anatase TiO nanoparticles (TiO-NP) were produced through a one-step solvothermal reaction using acetic acid or ethanol and titanium isopropoxide as solvothermal reaction systems. The crystalline structure, crystalline phase, and morphologies of synthesized materials were characterized using several techniques. According to our findings, both TiO-NR and TiO-NP were found to have polycrystalline structures, with pure anatase phases.

Solvothermally synthesized anatase TiO2 nanoparticles for photoanodes in dye-sensitized solar cells.

Many researchers working on the development of Dye-sensitized solar cells (DSCs) continue to focus on the synthesis of photoanode materials with high surface area, along with high light scattering ability to enhance light harvesting efficiency (LHE). On the other hand, dye packing density, which can also affect the LHE significantly, is often overlooked. Solvothermally synthesized anatase TiO nanoparticles (SANP) were obtained by a new and simple approach using a mixed solvent, ethanol and acetic acid.

The effect of amorphous TiO in P25 on dye-sensitized solar cell performance.

P25 is one of the most widely used forms of titanium(iv) oxide (TiO), routinely utilised in dye-sensitised solar cells (DSCs), where it is often employed as a control, in spite of its poorly defined nature and the typically low device efficiency (or possibly because of this). Work by Park in 2000 and later by Lin et al. suggests that the rutile component might not be to blame for this, as has often been claimed.

Aggregated mesoporous nanoparticles for high surface area light scattering layer TiO photoanodes in Dye-sensitized Solar Cells.

Hierarchically structured aggregates, consisting of TiO nanoparticles were produced via one-step solvothermal syntheses with a mixed solvent system containing both acetic acid and ethanol. Two of the resulting structures, one ~700 nm and the other ~300 nm in diameter, were found to be comprised of 8.5 nm and 10.
