• structural directing agents (SDAs) [97][98]. This way, the final material corresponds to the negative replica of the SDA. There are two principal templating methods: hard templating (or nanocasting) and soft templating [97]. Hard templating involves an exotemplating approach, where the precursor solidifies

• templating (exotemplating) [6][7]. In general, templating agents arrange in the surrounding environment in such a way to generate a porous system in the newly synthesized materials, which replicates the 3D structure of the template arrangement. Often, both shape and size of the resulting porous system are

Keywords: electrospinning; exotemplating; nanostructured solid solution; sol–gel chemistry; Stoeber process; ternary oxide; Introduction Ceria, CeO2, is well-known for its unique

• combination of electrospinning and exotemplating leading to hollow CeO2/ZrO2@SiO2 composite tubes. Firstly, after electrospinning of polystyrene fibers, the fibers were covered by an exotemplating step with a sol solution containing monodisperse silica particles obtained from a Stoeber process. This is

• and characterization of hierarchical microsized nanocrystalline ceria fibre mats Formation of ceria tubes without surfactant Ceria tubes were prepared by an exotemplating technique. After controlled ageing of a sol-precursor solution prepared from cerium ammonium nitrate (NH4)2Ce(NO3)6 in water and

Exotemplating by spray coating of an inorganic ceria sol was used as the technique to introduce the ceria after final calcination.
