Cu(II)Cr(III)-LDH: synthesis, characterization, intercalation properties and a catalytic application
- 54 Downloads
Optimum conditions were searched for the synthesis of Cu(II)Cr(III)-L(ayered)D(ouble)H(ydroxide), then the intercalation and catalytic properties were studied. For the optimization, the molar ratio of the metal ions, pH, temperature and ageing time were systematically varied. Applying this LDH as the host, the anionic form of l-proline was intercalated into the interlayer space with the direct anion-exchange method. For the structural characterization of the pristine and the intercalated products, powder X-ray diffractometry, IR spectroscopy, scanning and transmission electron microscopies as well as thermal methods were used. The catalytic properties were investigated in the oxidation of allylic alcohol. The reaction parameters such as the solvent, oxidant and the catalysts treatment were varied.
