Abstract Low‐cost, millimeter‐thick chitosan‐based sponges are engineered with zinc oxide (ZnO) using atomic layer deposition (ALD) to create a multifunctional nanocomposite for the potential application in water remediation and self‐regeneration via solid‐state photocatalysis. Initially, non‐porous chitosan films served as control samples study ZnO growth mechanism its impact on biopolymer's optical chemical properties. Subsequently, porous further explore photocatalyst infiltration into matrix. The characterization of chitosan/ZnO hybrid material is performed spectroscopic ellipsometry, X‐ray photoelectron spectroscopy, UV–vis, photoluminescence, infrared analyzing effect varying number ALD cycles, resulting different thicknesses range 5–30 nm A reaction‐limited model found strong interactions between amino groups significantly enhance stability impart photocatalytic features. Adsorption tests Direct Blue 78 dye demonstrated high removal efficiency, capacities up 2000 mg g −1 , surpassing pristine sponges, which degrade water. Electrostatic sulfonate protonated moieties identified key this performance. Preliminary experiments Naproxen confirms ZnO‐coated sponges' ability pollutants, showcasing technology producing bio‐based, photoactive materials sustainable treatment.
