A novel polydopamine-coated bacterial cellulose/g-CN membrane for highly efficient photocatalytic degradation of methylene blue.

Photocatalytic oxidation emerges as an eco-friendly approach for chemically degrading water-borne organic pollutants. Establishing a more sustainable process for synthesizing photocatalyst membranes with higher efficiency and reusability is crucial for advancing safe water remediation solutions. In this study, we present a novel photocatalytic membrane incorporating bacterial cellulose (BC), a naturally occurring biopolymer with an intricate fibrous network, and graphitic carbon nitride (g-CN), a visible light-responsive non-metal photocatalyst.
