Multifunctional Sponge Enables the High‐Efficient Photocatalytic Degradation of Dyes and Tetracycline through ZnS@Bi 2 S 3 @HNTs

demonstrates outstanding photocatalytic degradation performance against various dyes (RHB, MO, MB), achieving efficiencies exceeding 98% and retaining over 73% efficiency after five consecutive catalytic cycles. The photocatalytic degradation efficiency of tetracycline (TC) reaches 97.3%. The photodegradation mainly originated from hydroxyl radicals. This method has potential for an efficient photocatalytic system in environmental remediation.
