ZnO/g-C₃N₄ heterojunctions were synthesized by systematically varying the concentration of zinc nitrate hexahydrate, and the effect of this variation on the structural, optical, and photocatalytic properties was investigated using experimental techniques. The optical band gap energies were evaluated from UV–visible spectroscopy, revealing that the band gap of ZnO/g-C₃N₄ heterojunctions lies in...
