Effect of support acidity during selective hydrogenolysis of glycerol over supported palladium ruthenium catalysts - data

<p>The data set reports the role of the acidity of support during the selectivity hydrogenolysis of glycerol over supported bimetallic palladium-ruthenium catalysts. The PdRu nanoparticles were supported on a series of metal oxides and zeolitic supports <em>via</em> the modified impregnation method and tested for the liquid-phase hydrogenolysis of glycerol using gaseous hydrogen. The relative acid site densities of selected catalysts were determined by ammonia temperature-programmed desorption and pyridine desorption experiments. Based on these studies, we report a direct correlation between the catalytic activity (conversion & 1,2 propane diol yield) and two different acid sites (strong acid sites and very strong acid sites). Besides zeolite supported catalysts, TiO₂supported PdRu nanoparticles exhibits moderate catalytic activity however, this catalyst shows high selectivity for the desired C-O bond cleavage to produce C3 products over the undesired C-C bond cleavage to produce < C3 products. To further support the data presented in the article, the origina data for the GC analyses, TEM pictures (raw file) and Calibration plots using calibration mixtures are presented here. <br></p><p>Research results based upon these data are published at https://doi.org/10.1098/rsta.2020.0055<br></p><p><br></p>
