Photocatalytic Degradation of Dyes Using TpPa-COF-Cl2 Membrane

Year: 2025

Type: conference-paper

Abstract: Covalent organic frameworks (COFs) are photocatalysts composed of covalent bonds of light elements and free of toxic metals. COFs are highly active against dyes. Furthermore, we aimed to improve the utility of COFs by making them into membranes. In this study, by utilizing the cross-linked structure of calcium alginate, we succeeded in forming the photocatalyst TpPa-COF-Cl2 into a membrane without destroying its structure. This was confirmed by characterization such as FT-IR. In addition, methyl orange was decolorized at 450 nm, confirming the photocatalytic activity of the membrane.
