Abstract
Layer double hydroxide (LDH) is well known for its ability to intercalate anionic compounds. Most popular LDH is prepared only conventionally with bivalent and trivalent cations. In this study, Co-Ti LDH consisting of bivalent and tetravalent cations was prepared and characterized by chemical analysis, X-ray diffraction, IR spectra, thermal analysis and Scanning Electron Microscope (SEM). The experimental results indicate that the ageing procedure plays a vital role in the formation of Co-Ti LDH. The insertion of a cyanate anion into LDH was confirmed by chemical analysis and IR spectra. XRD patterns of the prepared LDH (Co-Ti-CNO) showed that the interlayer spacing of the LDH was 0.79 nm. The spacing was similar to that of usual LDH in which chloride or bromide anion is the guest. SEM images show that the morphology of Co-Ti LDH was a plate-like structure or a fibrous structure depending on the preparation conditions.
