MIL‐101(Cr) template method has been employed successfully to synthesize CuCr 2 O 4 /CuO composite. The synthesized sample was characterized by powder X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FT‐IR), high‐resolution transmission electron microscopy (HR‐TEM), scanning electron microscopy (SEM), X‐ray photoelectron spectroscopy, N 2 adsorption–desorption isotherm (BET) analysis, and UV vis‐ diffuse reflectance spectroscopy (UV‐DRS). The photocatalytic efficiency of the nanocomposite was evaluated towards the degradation of methylene blue (MB) dye and antibiotic tetracycline (TC) solution. The morphological studies confirmed that the CuO was uniformly dispersed on the CuCr 2 O 4 matrix. The CuCr 2 O 4 /CuO nanocomposite showed high degradation efficiency of about 90% in the presence of H 2 O 2 where the MB degradation reaction got completed in a mere 35 min and ~95% TC got degraded within 120 min.
