“…Therefore, there is always a need for an effective dye adsorbent system. Usually, photocatalytic degradation, − photoelectrocatalytic degradation, photodegradation, , photo-Fenton catalytic degradation, , Janus nanoabsorbents, nanocomposites, , activated carbon, , and biosorption methods − have been used to remove organic contaminants such as dyes and harmful chemicals from wastewater. However, phase-selective supramolecular organogelators having appropriate hydrophilic/hydrophobic sites are usually found to be promising in this process.…”

Simple, effective, and eco-friendly sugar-based phase-selective gelators were synthesized at a low cost. They showed high gelling ability toward a wide range of solvents at lower concentrations (minimum gelation concentration ∼0.3%). Preliminary tests reveal that these low molecular weight organogelators can immediately and phase-selectively gel benzene, toluene, petrol, and kerosene in water at room temperature. We also identified G13 in toluene as the good gelator, and the corresponding organogel proficiently removes water-soluble dyes from their concentrated aqueous solutions. This efficient removal of toxic organic solvents and dyes from water suggests promising applications in removing organic substances from contaminated water resources. The thermoreversible gel exhibits effective rechargeability up to five cycles of burning and gelation, which imply the flame stability of the gel. Interestingly, these compounds had a high detection ability toward Cu2+ ions with a state change from gel to the solution. The physical justification for gelation mechanisms and the molecular interaction with metal ions were further confirmed by computational studies.

The removal of organic dyes and pathogenic bacteria from contaminated water remains a significant challenge. In the present study, S-type heterojunction Ag2MoO4/ZnFe2O4 (AMO/ZFO) composite nanofibers were synthesized by electrospinning and co-precipitation and fabricated into photoanodes. It is found that the constructed S-type heterojunction of AMO/ZFO composites effectively inhibits the recombination of photogenerated carriers, in addition to the benefits of more exposed active sites and a greater specific surface area. When several properties are improved, AMO/ZFO composites exhibit excellent photoelectrocatalytic performance. The results demonstrate that under visible light irradiation, the photoelectrocatalytic degradation rate of AMO/ZFO-3 to methylene blue reached 76.2% within 50 min, and the killing rate of Salmonella was 83.6% within 80 min. The enhanced photoelectrocatalytic activity was due to the synergy of both electrochemical and photocatalytic effects. More importantly, after four testing cycles, AMO/ZFO-3 still has a better ability to kill pathogenic bacteria and degrade organic dyes due to its high stability. This work provides a feasible method for oxidizing organic dyes and pathogenic bacteria.

Adding noble metals and barium hexaferrite to TiO 2 creates novel magnetic plasmonic nanocomposites with high activity in the photodegradation of organic contaminants. In this work, we have synthesized BaFe 12 O 19 by microwave and sol−gel combustion (using green fuel, glucose) methods and TiO 2 by the sol−gel method. Then, noble metals (Pt and Pd) were deposited on BaFe 12 O 19 /TiO 2 by a reducing agent (glucose: green surfactant) under ultrasound waves. The samples were characterized. On the basis of XRD and SEM results, the composites are highly crystalline and impurity-free. TEM images and BET analysis indicated the samples have a suitable morphology. Furthermore, the magnetic analysis showed the addition of TiO 2 and noble metals to barium hexaferrite has led to the lower coercivity, but the synthesized nanocomposites still have the suitable magnetic properties (M sBaFe12O19/TiO2@Pt = 37, M sBaFe12O19/TiO2/Pd = 34, M rBaFe12O19/TiO2@Pt = 16, M rBaFe12O19/TiO2/Pd = 13.9 emu/g). UV−vis DRS spectra revealed the band gaps of BaFe 12 O 19 /TiO 2 @Pt and BaFe 12 O 19 /TiO 2 /Pd are 3.13 and 3.08 eV, respectively. Finally, BaFe 12 O 19 /TiO 2 @Pt and BaFe 12 O 19 /TiO 2 /Pd nanocomposites were used to degrade the anionic and cationic dyes under visible irradiation within 120 min. The highest percentage of degradation was related to methyl orange, around 96% and 92% by BaFe 12 O 19 /TiO 2 @Pt and BaFe 12 O 19 /TiO 2 /Pd, respectively. Indeed, Pt because of its high work function and electron affinity is more effective in photodegradation.
