Bisphenol A removal using visible light driven Cu2O/PVDF photocatalytic dual layer hollow fiber membrane

Bisphenol A (BPA) is amongst the endocrine disrupting compounds (EDCs) that cause illness to humans and in this work was removed using copper (I) oxide (Cu2O) visible light photo-catalyst which has a narrow bandgap of 2.2 eV. This was done by embedding Cu2O into polyvinyl-idene fluoride (PVDF) membr...
