Ceramic membranes with four MWCOs and pore size (50 kDa, 150 kDa, 300 kDa, and 200 nm) were modified via a sol-gel vacuum infiltration method with CeO₂, CeTiOx, and a dual-layer CeO₂+CeTiOx coating to promote ozone activation and hydroxyl radical (●OH) generation. Continuous-flow Hybrid Ozonation–Membrane Filtration (HOMF) experiments demonstrated that dual-layer modifications significantly enhanced degradation rates of carbamazepine, diclofenac, ibuprofen, and pCBA, with lower MWCO membranes exhibiting higher adsorption and retention. Scavenger tests using tert butanol confirmed the critical role of ●OH, while SEM, AFM, XRD, and MIP characterization revealed substantial changes in surface morphology and pore structure. This study is the first to systematically examine the interactions between ultrafiltration and microfiltration ceramic membranes with varying MWCO and tailored surface modifications, providing novel insights for optimizing catalytic ozonation for pharmaceutical degradation in water treatment Open Access funding provided thanks to the CRUE-CSIC agreement with Elsevier 6 2025-09-23T06:26:56Z 2025-09-23T06:26:56Z 2025-12 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion peer-reviewed http://hdl.handle.net/10256/27332 info:eu-repo/semantics/altIdentifier/doi/10.1016/j.jeurceramsoc.2025.117635 info:eu-repo/semantics/altIdentifier/issn/0955-2219 info:eu-repo/semantics/altIdentifier/eissn/1873-619X Attribution 4.0 International http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Elsevier Journal of the European Ceramic Society, 2025, vol. 45, núm. 15, p. 117635 Articles publicats (ICRA)
