Large‐Scale Nonhydrolytic Sol–Gel Synthesis of Uniform‐Sized Ceria Nanocrystals with Spherical, Wire, and Tadpole Shapes

Spawning nanostructures: Uniform-sized ceria nanocrystals with sphere, wire, and tadpole shapes were synthesized from the nonhydrolytic sol–gel reaction of cerium(III) nitrate and diphenyl ether in the presence of appropriate surfactants. The picture shows a TEM image of a batch of tadpole-shaped nanowires (bottom left) and low-magnification and high-resolution TEM images of a single tadpole-shaped nanowire (right and top left, respectively).
