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.
