“…So far, CeO 2 with different sizes and morphologies such as nanorods [7], nanospheres [8], nanotubes [9], and nanocubes [10] have been synthesized in the last decade. It was proved that CeO 2 nanoparticles with different sizes and morphologies have better properties than general CeO 2 does.…”

Hierarchical CeO2 particles were synthesized by a hydrothermal method based on the reaction between CeCl3·7H2O and PVP at 270 °C. The flower-like CeO2 with an average diameter of about 1 μm is composed of compact nanosheets with thicknesses of about 15 nm and have a surface area of 36.8 m2/g, a large pore volume of 0.109 cm3/g, and a narrow pore size distribution (14.9 nm in diameter). The possible formation mechanism of the hierarchical CeO2 nanoparticles has been illustrated. The 3D hierarchical structured CeO2 exhibited a higher catalytic activity toward CO oxidation compared with commercial CeO2.

“…It is well known that the type of alkaline mineralizers (MOH, M = K, Na, Li) in the hydrothermal reaction also has an important in uence on the shape and size of product. This is mainly attributed to the fact that the formation rate of product is related to the cationic radius of mineralizers [24][25][26] . Up to now, the most commonly used mineralizer for preparing Bi 2 Fe 4 O 9 are NaOH and NH 4 OH [8][9][10][11][12][13]22) .…”

Bi 2 Fe 4 O 9 nanoplatelets were successfully prepared via hydrothermal method using KOH as the mineralizer. The in uence of KOH concentration on the morphology of the products was investigated. It is found that the thickness and edge length of as-prepared Bi 2 Fe 4 O 9 nanoplatelets can be tailored by adjusting the KOH concentration. With increase in the KOH concentration from 3 to 9 M, the thickness of nanoplatelets increases gradually, whereas their edge length exhibits a trend of decrease. A possible in uencing mechanism of the KOH concentration on the morphology of Bi 2 Fe 4 O 9 nanoplatelets is proposed on the basis of experimental results. The photocatalytic activity of Bi 2 Fe 4 O 9 nanoplatelets was investigated by the degradation of methylene blue under simulated sunlight irradiation, indicating that they possess an appreciable photocatalytic activity. Furthermore, the as-prepared Bi 2 Fe 4 O 9 nanoplatelets present good photocatalytic reusability. Magnetic hysteresis loop measurement shows that the Bi 2 Fe 4 O 9 nanoplatelets exhibit weak ferromagnetic behavior at room temperature.
