ABSTRACT = {A synergistic effect of adsorption and photocatalysis provides a key role ensuring high degradation efficiency. In this study, nanocellulose (nC) derived from oil palm empty fruit bunch (OPEFB) via delignification followed by acid hydrolysis was combined with CuO for methylene blue (MB) removal through a two-stage process: adsorption followed by photocatalysis. The nC content varied at 5%, 15%, and 25% by mass. Structural analyses revealed successful extraction of nC from OPEFB, with particle sizes of 260–310 nm, a surface area of 2.3 m<sup>2</sup>/g, and a pore diameter of 9.5 nm. The incorporation of nC improves CuO dispersion and stability while maintaining visible-light-responsive bandgap characteristics, resulting in a significant increase in MB removal from 43.6% (pure CuO) to 99.7% (CuO/nC 25%) within 60 min under UV irradiation. The nC contributes to rapid MB adsorption in the initial stage (0–15 min), followed by enhanced photocatalytic degradation in the later stage (15–60 min). This study highlights the potential of enhancing the adsorption and photocatalytic activities of CuO/nC composites for facile and efficient MB removal.},
