In summary, the hydrothermally prepared 2D\2D ternary nanocomposite was used as an efficient photocatalyst for the photodegradation of MB dye. The nitrogen-

photocatalytic efficiency under the visible light irradiation due to the improved photo active surfaces. Especially, in ternary nanocomposite Mg-Al LDH 2D nanoplates are vertically well aligned on the surface of the g-C3N4 2D nanosheets. This 2D/2D arrangement results effectively enhances the photocatlytic activity due to the efficient separation of photo-induced charge carriers and transfer by the incorporation of ZnO into LDH brucite layers. In addition, the g-C3N4 surface contributed to the efficient charge injection in the photocatalytic reaction. The novel g-C3N4\ZnO\Mg-
