Local structure of Pt and Pd ions in Ce(1-x)Ti(x)O(2): X-ray diffraction, x-ray photoelectron spectroscopy, and extended x-ray absorption fine structure

Baidya, T.; Priolkar, K.R.; Sarode, P.R.; Hegde, M.S.; Asakura, K.; Tateno, G.; Koike, Y. (Journal of Chemical Physics. 128(12); 2008; Article ID: 124711)

Ce(1-x-y)Ti(x)Pt(y)O(2-delta)(x=0.15; y=0.01) and Ce(1-x-y)Ti(x)Pt(y)O(2-delta)(x= 0.25; y=0.02 and 0.05) are found to be good CO oxidation catalysts [T.Baidya et al., J. Phys. Chem. B 110, 5262 (2006); T.Baidya et al., ...
Origin of enhanced reducibility/oxygen storage capacity of Ce(1-x)Ti(x)O(2) compared to CeO(2) or TiO(2)

Dutta, G.; Waghmare, U.V.; Baidya, T.; Hegde, M.S.; Priolkar, K.R.; Sarode, P.R. (Chemistry of Materials. 18(14); 2006; 3249-3256.)

We determine chemical origins of increase in the reducibility of CeO(2) upon Ti substitution using a combination of experiments and first-principles density functional theory calculations. Ce(1-x)Ti(x)O(2) ( x = 0.0-0.4) ...
Reducibility of Ce(1-x)Zr(x)O(2): origin of enhanced oxygen storage capacity

Dutta, G.; Waghmare, U.V.; Baidya, T.; Hegde, M.S.; Priolkar, K.R.; Sarode, P.R. (Catalysis Letters. 108(41702); 2006; 165-172.)

We combine first-principles calculations with EXAFS studies to investigate the origin of high oxygen storage capacity in ceria-zirconia solid solution, prepared by solution combustion method. We find that nanocrystalline ...
Ultra-low temperature CO oxidation activity of octahedral site cobalt species in Co sub(3) O sub(4) based catalysts: Unravelling the origin of unique catalytic property

Baidya, T.; Murayama, T.; Nellaiappan, S.; Katiyar, N.; Bera, P.; Safonova, O.; Lin, M.; Priolkar, K.R.; Kundu, S.; Rao, B.S.; Steiger, P.; Sharma, S.; Biswas, K.; Pradhan, S.; Nakka, L.; Malviya, K.D.; Haruta, M. (Journal of Physical Chemistry C. 123(32); 2019; 19557-19571.)

Co sub(3) O sub(4) with spinel structure shows CO oxidation activity at very low temperature under dry condition. This study aims at finding the origin of the unique catalytic activity of Co species in Co sub(3) O sub(4) ...
Understanding the anomalous behavior of Vegard's law in Ce(1-x)M(x)O(2) (M=Sn and Ti; 0 less than x less than or equal to 0.5) solid solutions

Baidya, T.; Bera, P.; Krocher, O.; Safonova, O.; Abdala, P.M.; Gerke, B.; Pottgen, R.; Priolkar, K.R.; Mandal, T.K. (Physical Chemistry Chemical Physics. 18(20); 2016; 13974-13983.)

The dependence of the lattice parameter on dopant concentration in Ce(1-x)M(x)O(2) (M = Sn and Ti) solid solutions is not linear. A change towards a steeper slope is observed around x approx 0.35, though the fluorite ...
