The　indiscriminate　of　tetracycline　(TC)　has　led　to　significant　environmental　and　health　concerns,　particularly　the　proliferation　of　antibiotic　resistance.　This　study　presents　a　visible-light　photocatalytic　composite　membrane　with　a　Z-scheme　heterojunction　to　improve　TC　removal　efficiency　and　address　the　challenge　of　catalyst　powder　recovery　in　practical　applications.　Firstly,　the　PI/NH2-UiO-66　(PNs)　composite　photocatalyst　was　synthesized　via　a　one-step　thermal　solvent　method.　Subsequently,　the　PVDF/MXene/PI/NH2-UiO-66　(PMPNs)　composite　fiber　membrane　was　successfully　fabricated　by　stably　loading　the　PNs　and　MXene　onto　PVDF　fiber　membranes　through　electrospinning.　Under　visible　light　irradiation,　the　removal　efficiency　of　TC　by　the　PMPN1.5　composite　fiber　membrane　could　reach　86.07　%　through　the　combined　effects　of　filtration,　adsorption,　and　photocatalysis.　Even　after　three　cycles,　the　recovery　rate　of　the　PMPN1.5　membrane　could　still　reach　86.16　%.　The　enhanced　photocatalytic　performance　was　due　to　the　Z-scheme　heterojunction　between　PI　and　NH2-UiO-66.　This　heterojunction　structure　enhanced　the　redox　capability　of　the　photocatalyst.　Additionally,　the　incorporation　of　MXene　facilitated　effectively　charged　carrier　transfer　at　the　heterojunction　interface,　prolonging　the　electron-hole　separation　time　and　further　improving　the　photocatalytic　capability.　This　study　successfully　integrates　photo-catalytic　technology　with　membrane　separation　to　develop　a　visible　light-responsive　composite　fiber　membrane　with　considerable　potential　for　treating　antibiotic-contaminated　wastewater.　The　developed　membrane　not　only　mitigates　fouling　but　is　also　easily　recyclable,　minimizing　the　risk　of　secondary　pollution.
