| Abstract
| - A concept is shown to fabricate mesoporous ceria thin films with a crystalline framework and a bimodalpore size distribution by evaporation-induced self-assembly followed by a suitable temperature treatmentand template removal strategy. The use of a suitable block copolymer ((CH2CH2CH2(CH)CH2CH3)79(OCH2CH2)89OH), “KLE”) and an ionic liquid template (leading to pores 3 nm in diameter) generated a bimodalpore system of deformed spherical mesopores of ca. 6 nm × 16 nm with the smaller pores being locatedin the matrix between the larger ones. The porosity was studied by a combination of quantitative SAXSanalysis, physisorption, AFM, and TEM, introducing a general methodology for a quantitative structuralcharacterization of such films.
- Mesoporous ceria thin films with a crystalline framework and hierarchical bimodal mesopore architecture are fabricated by evaporation-induced self-assembly using a block copolymer (ellipsoidal mesopores of 6 × 4 nm) and ionic liquid template (3 nm pores) and studied by a combination of SAXS analysis, physisorption, AFM, and TEM.
