Abstract
Layered double hydroxides derived Cu-Al metal oxides were found to be an efficient catalytic reagent for the reaction of indole benzaldehydes. In this report, we prepared series of (Cu/Al)-CO3 layered double hydroxides with the unchanging ratio of Cu/Al = 3 : 1 and it was subsequently calcinated in air at 500 oC. The materials were characterized by means of Inductively Coupled Plasma emission (ICP), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and, thermogravimetry (TG). The materials were calcinated at 500 oC and tested as catalysts in the alkylation reaction of indole with benzaldehydes.
