Photodegradation Activity of Nitrogen-rich Graphitic Carbon Nitride Intercalated ZnO\Mg-Al Layered Double Hydroxide Ternary Nanocomposites on Methylene Blue Dye

Herein, we report the preparation and visible light-triggered photocatalytic investigation of nitrogen-rich graphitic carbon nitride (g-C3N4) nanosheets intercalated ZnO\Mg Al LDH (2D\2D) ternary nanocomposite. The ZnO nanoparticles, unique structured LDH, and g-C3N4 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-C3N4 and even distribution of ZnO\Mg Al LDH over the g-C3N4 surface. This work offers a facile approach to prepare a novel visible light-response photocatalyst for photocatalytic dye degradation of organic pollutants.
