Abstract Complications accompanying photocatalyst stability and recombination of exciton charges in pollutants degradation has been addressed through the construction heterojunctions, especially S‐scheme heterojunction with strong distinctive redox centres. Herein, an BiOBr (BOR) g‐C 3 N 4 PO (CNPO) catalyst (BORCNPO) oxygen vacancy (Ov) was synthesized for levofloxacin (LVX) oxytetracycline (OTC) photodegradation under visible light. The 3D/3D BORCNPO possessed C−O−Br bridging bonds efficient charge transfer during fabrication heterojunction. In‐situ H 2 O formation affirmed by potassium titanium (IV) oxalate spectrophotometric method improved mineralization ability BORCNPO7.5 catalyst. Bi 0 surface plasmon resonance (SPR) enhanced involvement ⋅O − which increased reaction rate increasing cycling experiments. XPS radical trapping experiments supported mechanism high LVX times higher than OTC rate. Mineralization their intermediates were demonstrated florescence excitation emission matrix (FEEM) quadruple time flight performance liquid chromatography (QTOF‐HPLC). This work advances development highly stable catalysts heterostructure.

Influence of visible light LEDs modulation techniques on photocatalytic degradation of ceftriaxone in a flat plate reactor

Chemical Engineering Journal, Год журнала: 2024, Номер 482, С. 149175 - 149175

In this paper, the effect of light modulation on photocatalytic ceftriaxone (CEF) degradation in aqueous solution was investigated. The experimental set-up consisted a fixed bed reactor with flat plate geometry and visible LEDs for irradiation. Fe-N-codoped TiO2 photocatalyst immobilized polystyrene (PS) by solvent casting method to achieve structured (Fe-N-TiO2/PS), which loaded photoreactor. Raman UV–Vis diffuse reflectance spectroscopy confirmed presence Fe-N-TiO2 PS surface its uniform distribution polymer support. Various dimming techniques were tested variable duty-cycle values. particular, following modulations used: (FD), sinusoidal (S-VD), triangular (T-VD), square wave (SW-VD), saw-tooth (ST-VD), pulse (P-VD), pseudo-sinusoidal (PS-VD). optimal S-VD, an average fed current between 25 75 mA period 30 s. Indeed, using S-VD modulation, highest value apparent CEF kinetic constant (resulting 0.0082 min−1) total organic carbon (TOC) removal (70 %) achieved. By comparing electric energy consumption (EE/O) used work those found other literature studies dealing degradation, significant decrease EE/O evidenced. Moreover, toxicity test showed that treatment allowed significantly reduce when compared untreated effluent.
