Preparation and characterization of organic - inorganic layered nano hybrids by the self-assembly reaction of amino acid and metal hydroxide

Abstract

Layered organic – inorganic nano hybrids were prepared by the self-assembly reaction of magnesium hydroxide and calcium hydroxide with L-phenylalanine. Layered structures were confirmed by TEM images directly. Interlayer spacing of the layered hybrid was 1.61 nm in the case of magnesium hydroxide and 1.65 nm in the case of calcium hydroxide. It indicates the presence of bi layer structure of L-phenylalanine between the layers. Self-assembly reaction was also confirmed in the reaction of L-phenylalanine with the mixture of magnesium and calcium hydroxides. Interlayer spacing increased with an increase in the amount of calcium hydroxide from 1.61 nm to 1.65 nm.
