Ammonia temperature-programmed desorption (NH 3 -TPD) was used to study the acidities of CeO 2 and Ce 0.5 Zr 0.5 O 2 solid solutions. The NH 3 -TPD peaks of both CeO 2 and Ce 0.5 Zr 0.5 O 2 exist at 100-850 Β°C. The ratio of the lower and middle temperature peak areas to the higher temperature peak i
A tetragonal t-(Ce 0.5 Zr 0.5 )O 2 , (t), prepared from ceria and zirconia mixtures by a conventional ceramic method, was reduced at 1123 K and successively oxidized at 873 K to attain a novel tetragonal phase, t meta -(Ce 0.5 Zr 0.5 )O 2 (t meta ). The electrical conductivity t of t meta was measur
