Nanoscale La(OH)3 Hollow Spheres and Fine‐Tuning of Its Outer Diameter and Cavity Size

Abstract: Size control in advance: water‐in‐oil microemulsions exhibiting micelles of precisely adjusted size can be used to prepare La(OH)3 hollow spheres with fine‐tuned diameter and cavity size. Namely La(OH)3 hollow spheres are obtained with outer diameters ranging from 11 to 30 nm and an inner cavity from 2 to 17 nm.

“…[60] As already discussed, the micelle diameter can be adjusted by the water-to-surfactant ratio w (see Section 2.2). [63] These data are confirmed by TEM/ HRTEM images,w hich showed outer diameters of 11 AE 3, 20 AE 5, and 30 AE 5nmand mean cavity sizes of 2 AE 1, 7 AE 5, and 17 AE 5nm, respectively (Figure 11 a-c). [3,16] Following this approach, the outer diameter and cavity size of hollow nanospheres can also be adjusted.…”

“…La(OH) 3 nanotubes were obtained by adjusting the pH and reaction temperature under KOH (or NaOH) solution conditions using a hydrothermal method [18]. Leidinger et al synthesized La(OH) 3 hollow spheres with outer diameters of 11 $ 30 nm and an inner cavity of 2 $ 17 nm using a water-in-oil microemulsion method [26]. Wang et al synthesized La(OH) 3 nanorods by a hydrothermal method and examined their photocatalytic activities by testing the photodegradation of Congo red dye [5].…”
