Effectiveness of photocatalytic degradation of phenol in aqueous solution using semiconductor oxides (SO) prepared by a sol-gel method was examined. The physical and chemical properties of synthesized catalysts were investigated by X-ray diffraction (XRD), diffuse reflectance UV-Vis spectroscopy (DRS), and N 2 -adsorption measurements. The optimal conditions of the photocatalytic degradation of phenol using prepared titanium dioxide sample were defined.

“…Due to their large specic surface areas, iron oxide nanosheets and ower-like assemblies have been reported as high performance anode materials for lithium-ion batteries and dye-sensitized solar cells. 3,4 In addition mesoporous iron oxide hollow micro/nanospheres have been investigated as vehicles for controlled drug delivery, 5,6 microwave absorption, 7,8 sensing platforms 9 and waste water treatment. 10,11 Synthesis of iron oxide nanomaterials typically follows one of two synthetic pathways resulting in different nanostructure morphologies, namely nanosheets and ower-like assemblies 3,4,7,13,14,17 and hollow nanospheres and solid nanospheres.…”

Therefore the ability to synthesize multiple iron oxide nanostructures in one synthetic procedure only by altering reaction time and temperature is clearly advantageous.…”

This work reported an improved approach to the synthesis of iron oxide nanostructures using iron(III) chloride as the precursor and hexamethylenetetramine (HMTA) as the key auxiliary. A range of iron oxide (alkoxide) nanostructures including nanosheets, hierarchical flowers (assembled by thin nanosheets), mesoporous hollow nanospheres and solid nanospheres were obtained only by altering the reaction temperature from 180 C to 240 C in a single synthetic protocol. Supplementary experiments driven by reaction time were designed in order to further clarify the morphological evolution behaviors of these nanostructures, which discovered that the spherical morphology with the size of about 150-200 nm formed from the inside of micro-scaled flower-like clusters gradually by the condensing and weaving of curled nanosheets, suggesting that the hollow nanospheres were obtained consequently by the further condensation of incompact nanospheres with the assistance of the rearrangement of surfactant micelles, followed by the oriented attachment assembly and Ostwald ripening.
