Polyvinylidene Fluoride‐networked Sb 2 S 3 /CdS/Ag 2 S Membrane with Dual‐junction Exciton Dynamics for In‐depth Purification of Textile Printing/Dyeing Wastewater

Year: 2025

Type: article

Abstract: The textile printing/dyeing (TPD) wastewater poses a serious threat to ecological safety, and it is essential and challenging to alleviate this environmental issue. The sunlight‐driven catalysis technology is a promising strategy for wastewater purification. However, the photostability and recyclability of highly active photocatalysts are the main factors limiting its application in wastewater treatment. Herein, a double‐shell Sb 2 S 3 /CdS/Ag 2 S (SCA) ternary nanorods with type‐II and type‐I exciton dynamics was constructed to prepare the polyvinylidene fluoride networked hybrid membrane (PVDF/SCA). Due to the synergistically interacted multi‐phase interfaces and superior recyclability, this hybrid membrane exhibited excellent piezo‐photocatalytic in‐depth purification ability of industrial discharged TPD wastewater under the collaborative drives of ultrasonic mechanical energy and light energy following by a durably stable catalytic performance, surpassing most reported environmental photocatalysts. This study proposes a feasible strategy for in‐depth treatment of industrial discharged TPD wastewater to acceptable levels for discharge.
