Abstract MXene-based (nano)materials have recently emerged as promising solutions for antibiotic photodegradation from aquatic environments, yet they are limited by scalability, stability, and selectivity challenges in practical settings. We formulated Fe 2 O 3 -SiO /MXene ternary nano-photocomposites via coupled wet impregnation sonochemistry approach optimised tetracycline (TC) removal (the second most used worldwide) water using response surface methodology-central composite design (RSM-CCD). The photocatalysts containing various loading of /SiO (5–45 wt%) on the MXene with a range calcination temperatures (300–600 °C) RSM optimisation were synthesised, characterised regarding crystallinity properties, morphology, binding energy, light absorption capability, analysed TC degradation efficiency. 25FeS/MX-450 among all samples demonstrated superior efficiency photocatalytic (98%) under conditions (TC degradation: 39.75 mg/L, time: 68.28 min, pH: 5.57, catalyst dosage: 0.75 g/L). developed area, reduced band gap due to FeS nanoparticles incorporation improved within visible spectrum, played crucial role heterostructure matrix, enhancing photogenerated carriers’ separation transportation capabilities. photoreduction mechanism involved electron transfer MXene, engaging produce •O −, attributed high mobility MXene. Our findings such materials can underscore considerable potential nanomaterials pharmaceutical waterways.

Fully understanding the periodate (PI) activation system is still a great challenge, which calls for efficient heterogeneous catalysts with sophisticated structure. Herein, we developed "MOF-on-MXene" heterostructures. By constructing S-scheme heterostructures MXene/Z67450, internal electric field generated via Ti-O-Co bonds at interface, favoring excitation of photogenerated electrons, providing driving force accelerating charge transfer, and enhancing redox performances. Further contributed by synergy Co-N4 bonds, MXene/Z67450 composites exhibit enhanced ability activating to degrade organic pollutants building donor-catalyst-acceptor system. In presence light, degraded ∼100% tetracycline hydrochloride (TCH) in only 10 min. The active sites can react give intermediate MXene/Z67450-PI (*PI). As result, it efficiently reduced PI adsorption energy promoted decomposition formation holes/electrons, singlet oxygen (1O2) as well hydroxyl radical (•OH). addition, high stability, reusability, selectivity, environmental robustness. Our study provides research direction rationally designing MXene-based heterojunctions applying them

Abstract Photocatalysts of TiO 2 –CuO coupled with 30% graphene oxide (GO) were hydrothermally fabricated, which varied the to CuO weight ratios 1:4, 1:2, 1:1, 2:1 and 4:1 reduced form –CuO/reduced (rGO) photocatalysts. They characterized using XRD, TEM, SEM, XPS, Raman, DRS technologies. composites –CuO/GO degrade methylene blue when persulfate ions are present. Persulfate concentration ranged from 1, 2, 4 8 mmol/dm −3 in highest activity 4.4 × 10 –2 7.35 min −1 was obtained for (1:4) (1:1), respectively.

Abstract Conventional wastewater treatment processes are often unable to remove antibiotics with resistant compounds and low biological degradation. The need for advanced sustainable technologies from water sources seems essential. In this regard, the effectiveness of a spinning disc photocatalytic reactor (SDPR) equipped visible light-activated Fe 3 O 4 @SiO 2 -NH @CuO/ZnO core–shell (FSNCZ CS) thin film photocatalyst was investigated decomposition amoxicillin (AMX), representative antibiotic. Various characterization techniques, such as TEM, FESEM, EDX, AFM, XRD, UV–Vis-DRS, were employed study surface morphology, optoelectronic properties, nanostructure FSNCZ CS. Key operating parameters irradiation time, pH, initial AMX concentration, rotational speed, solution flow rate fine-tuned optimization. results indicated that highest (98.7%) attained under optimal conditions 60 min speed 350 rpm, 0.9 L/min, pH 5, an concentration 20 mg/L. Moreover, during more than 69.95% chemical oxygen demand 61.2% total organic carbon removed. After AMX, there is substantial increase in average oxidation state SDPR 1.33 1.94 3.2, respectively. Active species tests confirmed ·OH ·O − played dominant role decomposition. developed SDPR, which incorporates reusable robust CS photocatalyst, demonstrates promising potential compounds.
