Uso de materiales laminares tipo cobalto-molibdato como potenciales catalizadores en la transformación de limoneno

Abstract

Use of layered cobalt molybdate materials like potential catalysts in the transformation of limonene. Limonene catalytic transformation was carried-out with four cobalt and molybdenum-based materials: two ofthem were prepared by hydrothermal synthesis and co-precipitation, whereby layered materials were obtained (CoMox and CoMoy). The two remaining materials were obtained by means of calcination of the layered solids (CoMox500 y CoMoy350). The catalysts were characterized by X-ray Diffraction (XRD), Fourier Transformed Infrared Spectroscopy (FTIR), H2 Temperature-Programmed Reduction (TPR), Thermogravimetric Analysis (TGA), Differential Thermal Analysis (DTA) and Atomic Absorption Spectroscopy (AAS). The better selectivity was 26% for limonene oxide with CoMox500
