Resumen:
Herein, we investigated the effect of the support modification (Sibunit
carbon) with diazonium salts of Pd and Pd-Au catalysts on furfural
hydrogenation under 5 bars of H-2 and 50 degrees C. To this end, the
surface of Sibunit (Cp) was modified with butyl (Cp-Butyl), carboxyl
(Cp-COOH) and amino groups (Cp-NH2) using corresponding diazonium salts.
The catalysts were synthesized by the sol immobilization method. The
catalysts as well as the corresponding supports were characterized by
Fourier transform infrared spectroscopy, N-2 adsorption-desorption,
inductively coupled plasma atomic emission spectroscopy, high resolution
transmission electron microscopy, energy dispersive spectroscopy, X-ray
diffraction, Hammet indicator method and X-ray photoelectron
spectroscopy. The analysis of the results allowed us to determine the
crucial influence of surface chemistry on the catalytic behavior of the
studied catalysts, especially regarding selectivity. At the same time,
the structural, textural, electronic and acid-base properties of the
catalysts were practically unaffected. Thus, it can be assumed that the
modification of Sibunit with various functional groups leads to changes
in the hydrophobic/hydrophilic and/or electrostatic properties of the
surface, which influenced the selectivity of the process.
