A DFT study on CO oxidation on Pd4 and Rh4 clusters and adsorbed Pd and Rh atoms on CeO2 and Ce0.75Zr0.25O2 supports for TWC applications

Porous cerium dioxide hollow spheres and their photocatalytic performance

“…2,8,9 Notably, ceria is a vital component in three-way catalysts (TWCs) mainly due to its high degree of tolerance to reversible oxygenation-deoxygenation cycles without disruption of uorite lattice structure. [10][11][12] In the past few decades, various morphologies of ceria including cubes, octshedra, spheres, wires and rods have been investigated. Very recently, ceria with hollow a structure has been fabricated by various methods.…”

Several different charge transfer and Ce3+localization scenarios for Rh–CeO2(111)

“…As far as computational Rh adatom-ceria (111) studies are concerned, a few [18][19][20][21][22][23][24] have focused on chemical processes and/or Rh cluster formation but without presenting details for low coverage Rh/ceria structures, which are the focus of the present study (see also the recent review of defects on ceria 25 ). Two have reported low coverage Rh adatom structures on ceria(111), 21,26 showing that the most stable adatom site is in a three-fold hollow between three surface O ions.…”

Recent advances in hydrothermal synthesis of facet-controlled CeO2-based nanomaterials

“…Moreover, the theoretical simulation shows that Zr doping can increase the OVC of CeO 2 , which is beneficial for CO oxidation. 63 The lanthanide is also commonly used for doping CeO 2 64 due to its close ionic radius to Ce 4+ . Most lanthanide metal ions are trivalent and form nonequivalent doping with CeO 2 .…”
