A novel C‐TiO2/PCN (CNT) composite is designed for piezo‐photocatalytic ciprofloxacin (CIP) degradation. The twisty structure, n→π* electronic transition, and Step‐scheme heterojunction of CNT can respectively give rise to the promotion of piezoelectricity, light utilization, and charge separation, leading to much more efficient CIP degradation during the piezo‐photocatalysis than individual photocatalysis or piezocatalysis. Abstract Herein, a twisty C‐TiO2/PCN (CNT) Step‐scheme (S‐scheme) heterojunction is fabricated and applied to de...
