Synthesis of mesoporous cerium dioxide thin films with high crystallinity

In English

Författare

Summary, in English

Thin films of crystalline mesoporous cerium dioxide were prepared by using a template of a copolymer surfactant (Pluronics 123) at ambient conditions in ethanol. The synthesised ceria was produced via a direct calcination step, without using a gelling stage. The precipitated CeO<sub>2</sub> matrix was crystalline with a high surface area. The solution height over the synthesis vessel before the calcination step was found to play an important role in the direct calcination synthesis. The material was characterised by Transmission Electron Microscopy (TEM), and the specific surface area was determined by nitrogen adsorption (BET-method)
