Pharmaceutical residues in aquatic environments have the potential to induce bacterial resistance, subsequently complicating disease treatment and posing a substantial hazard to public health.This study demonstrates the production of carbon dots from Cassia fistula flowers using a hydrothermal process.The obtained carbon dots were then mixed with zinc oxide to create Face Creams [email protected] heterojunction photocatalyst exhibited notable enhancement in photocatalytic performance due to improved charge separation efficiency at the interface.

The CDs@ZnO-H400 catalyst effectively removed two medications, ciprofloxacin and paracetamol.Ciprofloxacin showed maximum photocatalytic efficiency, with 99.8 % degradation, while paracetamol exhibited a degradation efficiency of 75.1 %.

The stability of the synthesized photocatalyst was evaluated across four usage cycles using EDX-SEM, FTIR, and XRD techniques.The CDs@ZnO-H400 heterostructure photocatalyst maintained Heart Bracelet strong photoactivity even after the fourth cycle of usage.
