摘要：
Bi2WO6 nanoplates were successfully synthesized at 200 degrees C with bismuth citrate (C6H13BiN2O7 center dot H2O) and sodium tungstate dihydrate (Na2WO4 center dot 2H(2)O) as raw materials in hydrothermal environment. The phase composition and morphology were characterized by x-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy (TEM) and high-resolution TEM. The average sizes of the Bi2WO6 nanoplates were ca. 300 similar to 400 nm in lateral size and ca. 30 nm in thickness, respectively, and the nanoplates were parallel to (010) planes. To completely understand the growth mechanism of the Bi2WO6 nanoplates, a series of time-dependent tests were applied, and a possible mechanism was proposed. Additionally, Rhodamine (RhB) degradation testing was carried out to investigate the photocatalytic activity.
