Herein, we report the preparation and visible light‐triggered photocatalytic investigation of nitrogen‐rich graphitic carbon nitride (g‐C 3 N 4 ) nanosheets intercalated ZnO\Mg−Al LDH (2D\2D) ternary nanocomposite. The ZnO nanoparticles, unique structured LDH, and g‐C 3 N 4 are intercalated well by the hydrothermal treatment, showing a significant enhancement in the visible light absorption and corresponding photocatalytic activity. Formation of this new ternary nanocomposite was examined by using XRD, FE‐SEM, TEM, FTIR, EDX, Elemental mapping, XPS and UV‐Vis analysis. The ternary nanocomposite photocatalyst show remarkable performance towards the photodegradation of Methylene Blue (MB) dye. The ternary nanocomposite exhibited considerable improvement in the photocatalytic activity and is attributed to the N‐ rich g‐C 3 N 4 and even distribution of ZnO\Mg−Al LDH over the g‐C 3 N 4 surface. This work offers a facile approach to prepare a novel visible light‐ response photocatalyst for photocatalytic dye degradation of organic pollutants.
