Here we report the synthesis of platinum doped barium cerate and its use as catalysts for WGS reaction. It has been found that maximum CO conversion was obtained at 350 degrees C which enhanced after the first cycle. XPS analysis shows that after the first cycle more ionic Platinum species are present on the surface of the catalyst. Neutron diffraction at room temperature shows that the oxygen vacancies are in the O2 position and increases with increasing Pt substitution.</p>10aBaCeO310aNeutron diffraction10aPlatinum catalysis10aWGS reaction1 aJijil, Chamundi, P.1 aRajarajan, A., K.1 aDevi, Nandini1 aMittal, R.1 aChauhan, A., K.1 aMukhopadhyay, R.  uhttps://library.ncl.res.in/content/noble-metal-ions-incorporated-lattice-points-perovskites-water-gas-shift-activity-bace1-001371nas a2200217   4500008004100000022001400041245017200055210006900227260005700296300001400353490000800367520054200375653001100917653001700928653001300945653001700958653000800975100002600983700001801009856012601027       2014                        eng d  a1011-372X00aPt States in BaCe0.98Pt0.02O3-delta during start up and shut down operations under different conditions: stability and activity of ionic Pt in water gas shift reaction0 aPt States in BaCe098Pt002O3delta during start up and shut down o  a233 SPRING ST, NEW YORK, NY 10013 USAbSPRINGERcDEC  a2227-22320 v1443 a<p>Stability of Pt species in doped BaCeO3 perovskites under Water gas shift reaction conditions is studied using X-ray absorption spectroscopy and in situ powder X-ray diffraction. The catalyst BaCe0.98Pt0.02O3-delta has Pt in +2 oxidation state and is found to be stable in the ionic form under reaction conditions as well as under various highly reducing shut down and start up conditions. In-situ XRD under Water Gas shift reaction conditions also reveals the Pt ions to be highly stabilized in lattice and no egress is observed.</p>10aBaCeO310aDeactivation10aplatinum10aWGS reaction10aXPS1 aRajesh, Thattarathody1 aDevi, Nandini  uhttps://library.ncl.res.in/content/pt-states-bace098pt002o3-delta-during-start-and-shut-down-operations-under-different-0
