Studies from Khon Kaen University Have Provided New Information about Photocatalytics [Well-synthesized Carbon Dots From Flower Of Cassia Fistula and Its Hydrothermally Grown Heterojunction Photocatalyst With Zinc Oxide...].

A recent study conducted at Khon Kaen University in Thailand has explored the use of well-synthesized carbon dots from the flower of Cassia fistula and its hydrothermally grown heterojunction photocatalyst with zinc oxide (CDs@ZnO-H400) for the photocatalytic degradation of ciprofloxacin and paracetamol. The researchers found that the CDs@ZnO-H400 catalyst effectively removed both medications, with ciprofloxacin showing a maximum photocatalytic efficiency of 99.8% degradation and paracetamol exhibiting a degradation efficiency of 75.1%. The synthesized photocatalyst also demonstrated strong photoactivity even after four usage cycles. This research highlights the potential of using carbon dots and zinc oxide for the removal of pharmaceutical residues in aquatic environments, which can contribute to bacterial resistance and pose a hazard to public health.
