Abstract: This study presents a wastewater treatment approach utilizing heterogeneous photocatalysis-Fenton coupling technology. The experimental design employs photo-Fenton degradation of Rhodamine B as a teaching module for undergraduates. The sulfur-modified FeOCl (FeS/FeOCl) heterojunction catalyst is synthesized through an in-situ ion exchange reaction. Subsequent characterization focused on the catalyst’s structure, morphology and optical property, followed by evaluation of its photo-Fenton degradation efficiency for Rhodamine B. This experiment demonstrates straightforward operation with obvious phenomena. It is helpful to improve the experimental operation skills of undergraduates, cultivate their scientific research ability and enhance their environmental protection awareness.
