A charge carrier-non-quenching magnetic core implanted in nanocrystalline ZnO and deposited with metallic Ag for superior bactericidal and photocatalytic activities.

A high-performance doped photocatalysts for inactivation of total coliforms in superficial waters using different sources of radiation

“…Although Karunakaran et al (2016), among others, have proven high photocatalytic efficiency of mercury vapor lamps, the inactivation of microorganisms in our study was more efficient with UV-LED. According to Gonçalves (2003), the major factors contributing to reduced efficiency in mercury vapor lamps radiation are both mercury deposition on the lamp walls and case solarization.…”

Magnetic Particles Nanorod of ZnO/CuFe2O4 Prepared by Green Synthesized Approach: Structural, Optical and Magnetic Properties, and Photocatalytic Activity

“…This can be attributed to the formation of a new level between the valence band (VB) and conduction band (CB) of CuFe 2 O 4 by coupling with ZnO nanoparticles, which promotes transport mobility and further enhances the absorption. The reduction of the gap in the band energy of ZnO in composites is advantageous for its application as a photocatalyst 17,34 . This bandgap value ensures the suitability of the material as a photocatalyst in visible light or sunlight region.…”

Magnetic nano-biocomposite CuFe2 O4 @methylcellulose (MC) prepared as a new nano-photocatalyst for degradation of ciprofloxacin from aqueous solution

“…HCl and NaOH solutions (0.1 N) were used for adjusting pH. The effects of different concentrations of antibiotics (3, 5, 7, and 9 mg/L), pHs (3, 7, and 11), amounts of photocatalysts (0.025, 0.05, 0.1, 0.2, 0.3, and 0.4 g), and irradiation times (15,30,45,60,75, and 90 minutes) were investigated in the presence of UV-C lamp on the antibiotic removal efficiency. During the research stages, the investigated parameters were optimized.…”

“…Also, ferrite-based catalysts with high oxidation and radical hydroxyl ( • OH) generation in photocatalytic processes can decompose a wide range of organic pollutants (23). Recently, CuFe 2 O 4 has received attention as a multi-use compound due to its various advantages such as stability, monodispersity, low-cost, high photochemical stability, simplicity, and rapid separation over other catalysts for the pollutants degradation (24)(25)(26)(27)(28)(29)(30)(31). Magnetic photocatalytic properties provide a convenient way for separation of the photocatalyst from suspension.…”
