Reverse microemulsion synthesis of CeO2 nanopowder using polyoxyethylene(23)lauryl ether as a surfactant

A designed magnetic CoFe2O4–hydroxyapatite core–shell nanocomposite for Zn(II) removal with high efficiency

“…2 which is determined by water to surfactant ratio. At high oil concentration, small water droplets (nanoreactores) are formed within a continuous oil phase when a surfactant is added [30][31][32]. Therefore, the size of droplets determines the particle size, depending on the kind and amount of the surfactant [33].…”

Synthesis of aqueous nanodispersed nanocrysralline ceria suspensions by a novel organic/inorganic precipitation method

“…This is very difficult to achieve as nanoparticles with a size less than 5 nm have a strong tendency to agglomerate [11]. In fact, the quality of the synthesized powder changes with the preparation method [10].…”

“…However, the catalytic and physical properties of ceria are strongly dependent on the homogeneity of structure, particle size distribution and phase purity [10]. In most applications, non-agglomerated nanoparticles are required to avoid inhomogeneous mixing, poor sinterability and compromised quantum properties.…”

“…Among them, homogeneous precipitation is one of the most promising techniques because of its simplicity, the use of inexpensive starting materials and the commonly available apparatus [10].…”

Morphology‐Controllable Preparation of CeO2 Materials for CO2 Adsorption

“…. [69] According to the literature, [70] if the particles' size became smaller than the de Broglie wave length of the charge carriers, the confinement energy required for creating an electron/hole pair should be increased and resulted in blue shift of absorption band. [71] Compared with the curves of b and c in Figure 12, there was an absorption band blue shifted from 310 nm to 302 nm, which was attributed to the smaller particle size of the comet-like CeO 2 crystals (29.36 to 44.79 nm) and dandelion-like CeO 2 crystals (7.29 to 14.34 nm).…”
