Abstract: The reticular Bi2O3 photocatalysts were synthesized via heat treatment process using
cotton as template. XRD, SEM, TGA, UV-Vis diffusion spectra were employed to characterize the
phase structure, morphology, thermal stability and optical absorption properties of the samples.
Results indicated that cotton played an important role in the formation of reticular structure. The
flat Bi2O3 reticles with different diameter were staggered and overlapped, thus reticular Bi2O3
were formed. Using the degradation of MB as a model reaction, the photocatalytic and recycling
properties of the reticular Bi2O3 were compared with Bi2O3 powders. Results indicated that the
reticular structure materials showed better photocatalytic properties than Bi2O3 powders. The
decolorization efficiency of MB solution reached about 93% at irradiation time 100min and
remained above 85% upon repetition (4 times). In addition, the formation mechanism of reticular
Bi2O3 was discussed in detail.
