Development of a bimetallic Cu/Mg/MCM catalyst for glycerol hydrogenolysis to propanediol without external hydrogen
Abstract
-TPR. The XRD patterns of all the synthesized catalysts revealed diffraction peaks corresponding to a well-ordered two-dimensional hexagonal structure of the MCM support at low angles, along with the presence of CuO and MgO phases at higher angles. A progressive decrease in the surface area and pore volume was observed with increasing the Cu and Mg loading. The association of Cu with Mg in a synergistic interaction resulted in decreasing the reduction temperature, proving the occurrence of the MgO hydrogen spillover effect as the Cu content was greater than that of Mg. The performance of all catalysts was assessed in glycerol hydrogenolysis reactions without the addition of external hydrogen gas to investigate the influence of Cu/Mg loading on the MCM-supported catalyst efficiency for the production of 1,2-PDO and 1,3-PDO.
