Visible-Light-Induced Graphitic–C₃N₄@Nickel–Aluminum Layered Double Hydroxide Nanocomposites with Enhanced Photocatalytic Activity for Removal of Dyes in Water

One of the major challenges in photodegradation of organic dyes is designing a visible light active and highly efficient photocatalyst that can degrade both cationic and anionic dyes. To design such an ideal catalyst, this work synthesized graphitic-C3N4@NiAl layered double hydroxide nanocomposites (g-C3N4@NiAl-LDH NCPs) with various g-C3N4 contents through a convenient and high-yield method. The photocatalytic process was optimized by...
