Abstract
This paper presents the development of a mechanically stable and self-healing hydrogel for the degradation of dyes in wastewater. The hydrogel is based on cellulose-derived co-polydopamine@Pd nanoparticles, creating a dynamic catechol redox system that provides stable mechanical properties and self-healing. A graphene oxide membrane is grafted onto the surface to regulate water permeability and protect the hydrogel structure. The hydrogel demonstrates high catalytic activity for both anionic and cationic dyes, maintaining performance over multiple cycles.
