摘要: Abstract Uniform nonagglomerated nanoparticles (∼12 nm) with equiaxed shape and high specific surface area (∼100 m2 g−1), consisting of Pr-doped ceria solid solutions (Pr/Ce mol ratio⩽0.2) have been prepared by aging at 100 °C for 2 h aqueous cerium (III) nitrate, praseodymium chloride hexamethylenetetramine. The Pr cations in such were trivalent, which induced a unit cell expansion.
