Cobalt chromium-layered double hydroxide, α- and β- Co(OH) and amorphous Cr(OH): synthesis, modification and characterization.

Cobalt-chromium layered double hydroxide (CoCr LDH), α- and β- Co(OH) and amorphous Cr(OH) have been synthesized under different reaction conditions. The obtained CoCr LDH was modified by stearic acid (SA) and sodium stearate (SS). The obtained samples have been characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM), Ultraviolet-visible- (UV-Vis), Fourier transform infrared- (FTIR) and Energy-dispersive X-ray- (EDX) spectroscopy.
