High performance, recoverable Fe3O4ZnO nanoparticles for enhanced photocatalytic degradation of phenol

Novel magnetically separable g-C3N4/AgBr/Fe3O4 nanocomposites as visible-light-driven photocatalysts with highly enhanced activities

“…These photocatalysts are composed of magnetic and photoactive materials. Thus, there are extensive attempts in searching for highly active visible-light-driven magnetic photocatalysts made from cost-effective and earth abundant elements [8][9][10][11][12].…”

The assessment of the photocatalytic activity of magnetically retrievable ZnO coated γ-Fe2O3 in sunlight exposure

“…The oxides of iron, namely α-Fe 2 O 3 (hematite), γ-Fe 2 O 3 (maghemite) and Fe 3 O 4 (magnetite) are the potential candidates in this regard and a number of studies are reported in the literature on the use coated magnetic iron oxide nanoparticles (MION) for the conventional purification of wastewater conventionally [17]. The visible light active magnetically separable Fe 3 O 4 @AgBr-ZnO nanocomposite and Fe 3 O 4 -ZnO nanoparticles were studied for the photocatalytic degradation of RhB dye and phenol, respectively [18][19]. In the recent…”

Synthesis, Characterization, and Photocatalytic Activity of Fe3O4@Zno Nanocomposite

“…From Table 1, it can be clearly seen that by increasing the dye concentration from 10 ppm to 40 ppm, the photodegradation efficiency of MB dye solution decreases from 100% to 52%. The photodegradation efficiency phenomenon relates to the formation of hydroxyl (*OH) and superoxide (*O -) radicals that are the primary reactive species in the photocatalytic oxidation of water pollutants (Mohamed et al, 2012;Feng et al, 2014). As the concentration of MB dye solution increases, the intensity of light and illumination is fixed, so that the photons entering the MB dye solution decrease and only a few photons of the catalyst.…”
