Defective WO3 nanoplates controllably decorated with MIL-101(Fe) nanoparticles to efficiently remove tetracycline hydrochloride by S-scheme mechanism

•S-scheme MIL-101(Fe)/WO3 heterojunction has been prepared successfully.•The as-prepared heterojunction shows a superior photocatalytic degradation activity.•The S-scheme photocatalytic mechanism is well verified.•h+ is main active radical in photodegradation over MIL-101(Fe)/WO3 heterojunction.
