Using water flow energy in the environment for water treatment is a feasible solution to alleviate energy shortages and environmental pollution. This work prepared a Cu 2 O@MoS 2 /PVDF modified pipeline with superior piezoelectric properties for norfloxacin (NOR) degradation. The piezoelectric coefficient d 33 of Cu 2 O@MoS 2 /PVDF increased by 27.7 % compared with PVDF. The piezoelectric current response test demonstrated that Cu 2 O@MoS 2 /PVDF had a higher current response than PVDF. FTIR showed that the presence of Cu 2 O@MoS 2 significantly increased the piezoelectric β -phase content of PVDF. The Cu 2 O@MoS 2 /PVDF pipeline exhibited the best degradation efficiency of 99.3 % within 40 min when the flow rate reached 1.389 L min −1 . O 2 – and OH have been shown to play an important role in NOR degradation and the possible degradation mechanism and pathways of NOR were proposed. This work provides a promising method for the efficient and green treatment of organic pollutants in water by using water flow energy and has practical application significance.
