Platelike crystal growth of Zn-Al layered double hydroxide by hot water treatment of sol-gel derived Al2O3-ZnO films on glass substrate
We have successfully immobilized Zn-Al layered double hydroxide (LDH) directly on glass substrates through the sol-gel method with hot water treatment. Al2O3-ZnO thin films were originally prepared on glass substrates by the sol-gel method with a heat treatment at 400 degrees C for 30 min, and then the films were immersed in distilled water at 100 degrees C for 15 min to form nanocrystalline Zn-Al LDH with hexagonal structure.
