XRD pattern showed the presence of Cu(+) species in the activated Cu: Al nano catalyst. Although Cu(+) is catalytically inactive in glycerol hydrogenolysis reaction, the presence of Cu(+) helps to stabilize the particle size in a narrow range of 7-11 nm by inhibiting the sintering of copper particles under reaction conditions.</p>10a110a2-Propanediol10aCu:Al nano catalyst10aGlycerol10aSelective hydrogenolysis1 aMane, Rasika, B.1 aHengne, Amol, M.1 aGhalwadkar, Ajay, A.1 aVijayanand, Subramanian1 aMohite, Pravin, H.1 aPotdar, Hari, S.1 aRode, Chandrashekhar, V.  uhttps://library.ncl.res.in/content/cual-nano-catalyst-selective-hydrogenolysis-glycerol-12-propanediol-0
