Characterization of mesoporosity in ceria particles using electron microscopy. by Shih, S, Herrero, P, Li, G, Chen, C, Lozano-Perez, S

“…The geometry and three-dimensional (3D) morphology of the ceria particles synthesized by spray pyrolysis (SP) from two different precursors--cerium acetate hydrate and cerium nitrate hydrate (CeA and CeN ceria particles)--were characterized by transmission electron microscopy and electron tomography. Results were compared with surface area measurements, confirming that the surface area of CeA ceria particles is twice as large as that of CeN ceria particles. …”
