Abstract

One-dimensional fibers of Bi₂MO₆ (M = Mo, W) have been prepared for the first time via electrospinning followed by heat treatment. The morphologies and crystal structures of as-prepared products were controlled by tuning the post heat treatment temperature. With the increase of the post heat treatment temperature, it was found that the morphologies of the obtained Bi₂MoO₆ changed slowly from fibers to rods, whereas the morphologies of the Bi₂WO₆ samples transformed gradually from fibers to porous fibers. The average diameters of the Bi ₂MoO₆ and Bi₂WO₆ fibers varied from 400 nm to 1 μm and were related to the heat treatment temperature. The photocatalytic activities for the photo-degradation of Rhodamine B (RhB) and Methylene blue (MB) over Bi₂MO₆ (M = Mo, W) were evaluated under the irradiation of simulated solar light. The results showed that RhB can be decomposed in 1 h and MB can be photo-degraded within 2 h.
