Examination of the photocatalytic activity of differently shaped bismuth tungstate microcrystals
In this study, Bi2WO6 photocatalysts with different morphologies were obtained by a one-step hydrothermal method. The resulted 3D structures (e.g. “flowers”) (d ≈ 2 µm) consisted from individual nanoplates. The synthesis procedure involved acetic acid, a surfactant (Triton X100) and a shaping agent,...

Summary: | In this study, Bi2WO6 photocatalysts with different morphologies were obtained by a one-step hydrothermal method. The resulted 3D structures (e.g. “flowers”) (d ≈ 2 µm) consisted from individual nanoplates. The synthesis procedure involved acetic acid, a surfactant (Triton X100) and a shaping agent, such as urea, thiourea and glycine. The effect of these compounds were also investigated in-detail. The crystallization was performed using the well-known hydrothermal method. The above mentioned morphological changes significantly influenced the photocatalytic activity, which was evaluated successfully by the degradation of Rhodamine B (RhB) under UV irradiation. |
