CoFe2O4 has potential for application as a magnetically recoverable visible-light photocatalyst, but its photocatalytic activity is encumbered by the high recombination probability of photogenerated holes (h+) and electrons (e–). This work was undertaken to boost photocatalysis through coupling with conjugated poly(vinyl chloride) derivative (CPVC). An easily implementable solvothermal−liquid solid mixing−evaporation solvent−pyrolysis method exploited synthesize CoFe2O4/CPVC nanocomposites. The capabilities products were assessed photocatalyzing reduction Cr(VI) under (λ > 420 nm). results demonstrate that optimal nanocomposite (CoFe2O4/CPVC-2) markedly heightened (3.6 times CoFe2O4) competent reusability recoverable. Furthermore, CoFe2O4/CPVC-2 also shows superior performance toward treatment diluted Cr(VI)-containing passivation solution copper alloys. It deduced based on photoelectricity measurement increased chiefly attributed p–n heterojunction structure, which greatly elevates h+–e– separation transfer efficiency. When waste PVC plastic films (replacing new pure powder) utilized synthesis, obtained exhibited even better (4 CoFe2O4). not only made recoverable, efficient photocatalyst decontamination in water inspirational recycling produce high-valued photocatalysts.

A highly effective and unique AgBr-NiO binary heterojunction was developed using an one-pot sol-gel method. The physicochemical properties of the produced materials were carefully examined analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) analysis, transmission (TEM), Brunauer-Emmett-Teller (BET), ultraviolet-visible diffuse reflectance spectroscopy (UV-vis-DRS), Fourier transform infrared (FTIR), photoluminescence (PL). mesoporous nature high surface revealed by BET analysis. composite showed greater photocatalytic degradation efficiency than bare AgBr NiO when exposed to visible light for colored anionic dye rhodamine B (RhB) bisphenol (BPA), a colorless endocrine-disrupting contaminant (EDC), resulting in activity RhB (97.6% 11 min) BPA (85% 120 min). Additionally, notable decrease TOC over time observed under similar reaction conditions photo-mineralization examination both model pollutants. Trapping tests conducted determine which reactive oxygen species (ROS) involved process. plausible Z-scheme mechanism this n-p proposed explain formation e-/h+ pairs induced light. work facilitates development recyclable photocatalyst characterized biological low toxicity.
