Abstract

En 中文

• Magnetic SA beads integrate lipase and CeO2@Bi2WO6 interfaces. • An S-scheme interface preserves strong redox-active charge carriers. • Enzymatic ester hydrolysis accelerates photocatalytic DMP oxidation. • DMP removal reached 99.12%, with enhanced but incomplete mineralization. • The coupled beads enable magnetic recovery and reduced residual toxicity.
