ZnAl 2 O 4 spinel nanoparticles and g-C 3 N 4 /ZnAl 2 O 4 nanocomposites were successfully synthesized by co-precipitation method. The influence of g-C 3 N 4 loading contents on structural, morphological and optical properties was investigated by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis diffuse reflectance spectroscopy (DRS), respectively. The peak intensity of g-C 3 N 4 increased as a function of g-C 3 N 4 loading contents. The optical band gap values of g-C 3 N 4 /ZnAl 2 O 4 nanocomposites were 3.10, 2.84, 2.82 and 2.80 eV when g-C 3 N 4 loading contents were increased from 0 to 10, 20 and 30%, respectively. The photocatalytic activity increased as a function of g-C 3 N 4 loading content. The 30% g-C 3 N 4 /ZnAl 2 O 4 nanocomposites exhibited highest MB degradation of about 100% under visible light irradiation for 360 min.
