Structural characteristics of AC and graphite materials were found to greatly affect the reducibility and particle size of supported Ru and hence, the activity and product distribution in glycerol hydrogenolysis. XRD of graphite materials showed distinctly (002) plane having highly organized layered structure and the peak intensity decreased in the order of Ru/KS150 &gt; Ru/HSAG100 &gt; Ru/KS6 due to decrease in the graphite sheet thickness. In Raman, the intense D band in HSAG100 compared to that in KS6 and KS150 samples indicated its highly amorphous nature or mixed carbon hybridization. Glycerol conversion for Ru on AC was higher than that on graphite and among different graphites, it showed a descending activity order of Ru/KS6 &gt; Ru/HSAG100 &gt; Ru/KS150. The product distribution for AC and HSAG100 supported Ru was similar, giving 1-propanol (45%) alongwith 1,2-propanediol (1,2-PDO) (37%) and 1,3-propanediol (1,3-PDO) (9–11%). For graphite supports, availability of Ru although bigger in size (4–5 nm), would be higher on the surface than in case of AC which formed deep hydrogenolysis products like 1-, 2- propanol, ethanol etc.</p>10aactivated carbon10aAmorphous carbon10acatalysis10aGlycerol10aGlycerol conversions10aGlycerol hydrogenolysis10agraphite composites10aGraphite supports10aHydrogenolysis10aHydrolysis10alayered structures10aParticle size10aProduct distributions10aPropanediols10aPropanol10aSelectivity behavior10aStructural characteristics10aStructural effect10aStructural effects1 aMane, Rasika, B.1 aPatil, S.1 aShirai, Masayuki1 aRayalu, Sadhana, S.1 aRode, Chandrashekhar, V.  uhttps://library.ncl.res.in/content/influence-carbon-based-supports-selectivity-behavior-diols-and-propanol-ru-catalyzed
