Bacteria-infected osteomyelitis is life-threatening without effective therapeutic methods clinically. Here, a rapid and strategy to treat through ferroelectric polarization interfacial engineering of BiFeO3 /MXene (Ti3 C2 ) triggered by ultrasound (US) reported. Under US, the induces formation piezoelectric field. US cavitation effect induced sonoluminescence stimulates /Ti3 produce photogenerated carriers. With synergistic action electric field Schottky junction, accelerates separation electrons holes simultaneously inhibits backflow electrons, thus improving utilization polarized charges consequently enhancing yield reactive oxygen species under US. As result, 99.87 ± 0.05% Staphylococcus aureus are efficiently killed in 20 min with assistance ultrasonic heating. The theory proposed, which brings new insight for developing responsive materials used diagnosis therapy deep tissue infection other acoustoelectric devices.

Oxygen Vacancies Trigger Rapid Charge Transport Channels at the Engineered Interface of S‐Scheme Heterojunction for Boosting Photocatalytic Performance

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(31)

Опубликована: Май 9, 2024

Abstract Although oxygen vacancies (Ovs) have been intensively studied in single semiconductor photocatalysts, exploration of intrinsic mechanisms and in‐depth understanding Ovs S‐scheme heterojunction photocatalysts are still limited. Herein, a novel photocatalyst made from WO 3 ‐Ov/In 2 S with at the heterointerface is rationally designed. The microscopic environment local electronic structure well optimized by Ovs. Femtosecond transient absorption spectroscopy (fs‐TAS) reveals that trigger additional charge movement routes therefore increase separation efficiency. In addition, synergistic effect on thermodynamic kinetic parameters photocatalysts. As result, optimal photocatalytic performance significantly improved, surpassing component ‐Ov (by 35.5 3.9 times, respectively), as /In heterojunction. This work provides new insight into regulating photogenerated carrier dynamics also helps design highly efficient

Synthesis and Photocatalytic Application of Magnetic CoFe₂O₄/Conjugated Poly(vinyl chloride) Derivative Nanocomposite

Langmuir, Год журнала: 2024, Номер 40(31), С. 16642 - 16652

Опубликована: Июль 25, 2024

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.
