Abstract: Abstract: Mesh-like bismuth oxide single crystalline nanoflakes were synthesized via a bismuth oxalate precursor way. During the synthesis procedure bismuth oxalate precipitate was hydrothermally treated, and variation of the pH value of synthesis solution as well as the addition of l-lysine could effectively tune the crystal phase and morphology of the bismuth oxalate precursor. Depending on the crystalline phase of the precursors and the calcination temperature, monoclinic α-Bi2O3 and tetragonal β-Bi2O3 were selectively obtained. Optical properties of the Bi2O3 materials were investigated by UV–vis absorption and the results proved that bismuth oxides were visible light responsive. Photodegradation of rhodamine B was used as a model reaction to test the photocatalytic activity of the Bi2O3 samples. The photocatalytic activity of bismuth oxides was related to its crystalline phase and morphology. [ABSTRACT FROM AUTHOR]
