Abstract:

Novel nanosheet-assembled Bi12SiO20 microcubes were prepared via a facile hydrothermal synthesis approach. The phase and morphology of the product were characterized by X-ray diffraction, energy dispersive spectrometry, selected area electron diffraction, X-ray photoelectron spectrometry, high resolution transmission electron microscopy and scanning electron microscopy. Experimental results indicated that as-prepared Bi12SiO20 sample was assembled by many nanosheets. Some influencing factors including reaction time, temperature and the presence of additives(e.g., polyacrylamide, sodium citrate and sodium hydroxide) were revealed to play crucial roles in the generation of Bi12SiO20 nanoarchitecture. Moreover, the photocatalytic experiments indicated that the as-prepared Bi12SiO20 product exhibited excellent photocatalytic activities and the degradation rate of RhB could reach to 97.5% under the irradiation of UV-Vis light.
