The effect of pH on the formation of host-guest type material: zinc-aluminium-layered double hydroxide-4-chlorophenoxy acetate nanocomposite

Layered organic-inorganic hybrid nanocomposite material containing 4-chlorophenoxy acetate (4-CPA) in an inorganic interlayer was prepared using 4-CPA as guest anion in Zn-Al layered double hydroxide inorganic host by direct precipitation method at various pHs. A well-ordered nanolayered organic-ino...
