ABSTRACT Organic dyes and drug‐resistant bacteria are posing a potential threat to human health ecology. Graphite phase carbon nitride (g‐C 3 N 4 ), because of its good light absorption performance, stability, suitable energy band structure, has applications in photocatalysis. Herein, oxygen doped (O‐CN) MXene Ti C 2 (TC) were physically mixed form heterojunction. The effect the ratio between O‐CN TC on photocatalytic performance was studied. Then O‐CN/TC‐2 dispersed PVA solution. Subsequently, solution electrospinning into flexible nanofiber membranes POCNTC‐2. POCNTC‐2 composite smooth uniform, average diameter 390 ± 2.7 nm. maximum removal efficiency membrane for MB (10 mg/L) reached 94.1% within 240 min. Meanwhile, it had favorable cycle stability. According bacteriostatic results, zone diameters 8% against Escherichia coli Staphylococcus aureus could reach 24 0.2 16 mm, respectively, rates 92% 87%, respectively. Overall, excellent organic materials antibacterial properties gave POCNTC great application field environmental purification.
