In this study, CuO nanoparticles supported on the seashell (CuO NPs/seashell) was prepared using Rumex crispus seeds extract as a chelating and capping agent. The prepared nanocomposite was characterised by Fourier transform infrared spectroscopy, X‐ray diffraction, field emission scanning electron microscopy, energy‐dispersive X‐ray spectroscopy and transmission electron microscopy. The particle size of CuO NPs on the seashell sheets was in the range of 8–60 nm. Catalytic ability of CuO NPs/seashell was investigated for the reduction of 4‐nitrophenol (4‐NP) and Congo red (CR). It was observed that catalyst can be easily recovered and reused several times without any significant loss of catalytic efficiency.
