Synthesis of magneto-plasmonic Au-Ag NPs-decorated TiO2-modified Fe3O4 nanocomposite with enhanced laser/solar-driven photocatalytic activity for degradation of dye pollutant in textile wastewater

Recent Advances in Plasmonic Photocatalysis Based on TiO2 and Noble Metal Nanoparticles for Energy Conversion, Environmental Remediation, and Organic Synthesis

“…Recently such magneto-plasmonic photocatalyst was reported for the degradation of rhodamine-6G (Rh6G) in textile wastewater. [238] The ternary Au-Ag@ TiO 2 @Fe 3 O 4 photocatalyst exhibits approximately four times higher activity than bare TiO 2 catalyst. Further, as prepared photocatalyst shows recyclability up to five cycles without any loss in catalytic activity.…”

Synthesis of Magnetic Targeted Cellulose Composite Decorated with Poly(AA-DMC) for Synergistic Adsorption Degradation of Congo Red from Organic Wastewater

“…13, the saturation magnetization (Ms) values of the MnFe2O4 and MnFe2O4@Cel-g-p(AA-DMC) were 35.44 and 12.89 emu•g -1 at 18155 and Oe, respectively (Mady et al 2019). No doubt the saturation magnetization value decreased relatively along with the composition of the non-magnetic modified cellulose (Amoli-Diva et al 2019). Meanwhile, the magnetic coercivity (Hc) were 7.8111 and 15.6069 Oe, respectively.…”

Concurrent photocatalytic degradation and filtration with bi‐plasmonic TiO 2 for wastewater treatment

“…A laser-assisted reduction technique was used to produce plasmonic magnetic TiO 2 photocatalysts using our previously reported method [21] with some modifications. Briefly, 0.2 g of the above prepared TF NPs was transferred into a 25-ml beaker containing gold (III) chloride trihydrate (10 mL, 5.0 mM) and PVP (5 mL, 0.37% w/w in methanol) and placed on the top a shaker.…”

“…On the other hand, covering TiO 2 NPs onto a Fe 3 O 4 NPs core is a facile way to recycle this material because superparamagnetic systems can be conveniently collected, separated, or fixed by applying an external supermagnet [20]. Thus, for the first time, we prepared an Au-Ag NPs-decorated TiO 2 -modified Fe3O4 nanocomposite for enhanced laser/solar-driven photocatalytic activity for degradation of dye pollutant in textile wastewater in our previous work [21]. However, decorating bimetallic NPs still needs more investigation and the effect of sequence of metallic shells need more consideration.…”
