“…In comparison to the quantity of nanoparticles produced naturally or accidentally, nanoparticles synthesized for research or industrial purposes are a small minority. Iron oxide nanoparticles are an essential oxide, with many applications due to their non-toxicity [18][19][20][21][22]. There are many forms of iron oxide crystalline phases: Hematite α-Fe2O3, β-Fe2O3, Maghemite γ-Fe2O3, Epsilon Fe2O3 and Magnetite (Fe3O4).…”

The dye-sensitized solar cell (DSSC) is a cost-effective and simple-to-implement technology for future energy generation. It has a comparable power conversion efficiency (PCE) to traditional silicon solar cells while having lower material and production costs. Fe2O3 nanoparticles were synthesized by photo irradiation method using complexes solution of iron. The synthesized nanoparticles are characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and Uv.visable spectroscopy. Results show that nanoparticles have a uniform rhombohedral shape with an 11 to 29 nm average size. The hematite nanoparticles were applied to fabricate a novel Dye solar cell, with an energy conversion efficiency of about 2.5 % by (ITO/ ?-Fe2O3 Nps/ Dye (Rhodamine 6 G) /iodine / Ag film / ITO).

In the present work, magnetic iron oxide nanoparticles have been synthesized by photo irradiation method using complex solution of iron. The synthesized nanoparticles characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and Uv.visable spectroscopy. Results show that nanoparticles have uniform cubic shape with average size of 15 to 24 nm. The Fe3O4 nanoparticles were applied to fabricate novel Dye solar cell which has energy conversion efficiency about 11.5 % by (ITO/ iron oxide NPs / Dye (Rhodamine 6 G) /iodine / Ag film/ ITO).

Efficient and Rapid Photocatalytic Degradation of Methyl Orange Dye Using Al/ZnO Nanoparticles

ZnO and Aluminum doped ZnO nanoparticles (Al/ZnO NPs) were successfully synthesized by the sol-gel method. Together with the effect of calcination temperatures (200, 300 and 400 °C) and Al dosage (1%, 3%, 5% and 10%) on structural, morphological and optical properties of Al/ZnO NPs, their photocatalytic degradation of methyl orange (MO) dye was investigated. The calcination temperatures at 200, 300 and 400 °C in forming structure of ZnO NPs led to spherical nanoparticle, nanorod and nanoflake structures with a well-crystalline hexagonal wurtzite, respectively. The ZnO NPs calcined at 200 °C exhibited the highest specific surface area and light absorption property, leading to the MO removal efficiency of 80% after 4 h under the Ultraviolet (UV) light irradiation. The MO removal efficiency was approximately two times higher than the nanoparticles calcined at 400 °C. Furthermore, the 5% Al/ZnO NPs exhibited superior MO removal efficiency of 99% in only 40 min which was approximately 20 times enhancement in photocatalytic activity compared to pristine ZnO under the visible light irradiation. This high degradation performance was attributed to the extended light absorption, narrowed band gap and effective suppression of electron–hole recombination through an addition of Al metal.
