synthesis of high‐quality crystalline α‐MoO3 nanobelts

Abstract High‐quality crystalline MoO 3 nanobelts were successfully fabricated with a facile hydrothermal route by using common and inexpensive NaCl as a capping agent. The products are thoroughly characterized by the combination of different techniques. The results indicate that as‐prepared MoO 3 nanobelts have an orthorhombic crystal structure (α‐MoO 3 ) with growth preferential in the 001 direction, the size of the obtained MoO 3 nanobelts ranges from 200 nm to 300 nm in width and micrometers in length. The effects of the amount of NaCl on the morphology and size of the resultant MoO 3 were also investigated, it is clearly shown that the presence of appropriate amount of NaCl plays a crucial role in controlling the size and morphology of the obtained MoO 3 .
