The same powders were characterized hi detail by HR-TEM, XRD, XPS, and Raman methods. The study demonstrates that activity is determined by the relative fraction of the active crystallographic planes, not by the specific surface area of the powders. The physical study is a step toward quantitative evaluation of the relative contribution to activity of the different facets. The synthetic protocol permits fabrication of CeO2 nanostructures with preferentially grown active planes, and therefore has potential in developing catalytic applications and in nanocompositing.</p>10aceria10achemical activities10acrystal facets10ananocrystals10atexture coefficient1 aSreeremya, Thadathil, S.1 aKrishnan, Asha1 aRemani, Kottayilpadi, C.1 aPatil, Kashinath, R.1 aBrougham, Dermot, F.1 aGhosh, Swapankumar  uhttps://library.ncl.res.in/content/shape-selective-oriented-cerium-oxide-nanocrystals-permit-assessment-effect-exposed-facets-0
