Photocatalytic degradation of methylene blue on magnetically separable MgFe2O4 under visible light irradiation

Magnetically Separable MnxZn1-xFe2O4; (0.0 ≤ x ≤ 0.5) Nanostructures: Structural, Morphological, Opto-Magnetic, and Photocatalytic Properties

“…These magnetically responsive photocatalysts have main advantage over the conventional photocatalysts, because they can be recovered and recycled readily. Similar values are reported earlier by Shahid et al[53].The magnetic hysteresis (M-H) curves of the as-prepared Mn x Zn 1-x Fe 2 nanocrystals obtained from room temperature VSM measurement with the applied field ranging from -10000 to +10000 Oe is shown inFig. 10.From the VSM measurements, saturation magnetization (M s ), remanent magnetization (M r ) and coercivity (H c ) values are evaluated and are reported in Table 2.…”

Facile synthesis and photocatalytic performance of Mg2SnO4/SnO2 heterostructures

“…Semiconductor coupling can not only broaden the light absorption but also can highly separate the photoinduced electron-hole pairs, which ultimately obtains excellent photocatalytic activity [12][13][14]. Recently, inverse spinel structure oxide, such as Zn 2 SnO 4 , ZnAl 2 O 4 , and MgFe 2 O 4 , has been reported for its photocatalytic properties to decompose organic pollutants in aqueous solution under the UV light irradiation [15][16][17]. Many approaches, including sol-gel method, hydrothermal method, thermal evaporation, and solid-state method, had been developed for the fabrication of inverse spinel structure oxide.…”

Nanocrystalline Zn1− Co0.5Ni0.5 Fe2O4 ferrites: Fabrication via co-precipitation route with enhanced magnetic and electrical properties

“…The position of bands in FTIR confirmed the formation of ferrite structure i.e. spinel structure [10,19,31,32]. …”
