Abstract

Molybdenum trioxide nanostructures attract great interest for their potential applications in areas of electrode in batteries, semiconductors, electrochromic devices, and other advanced material fields. Herein we disclosed the atmospheric, catalyst-free, scalable, rapid, and morphology-controllable flame synthesis of a series α-MoO3 nanostructures from metallic molybdenum. Controlling the morphology and size of the high-quality nanostructures by means of modulating various combustion configurations including fuel/oxygen ratio, height of growth substrates, and density of molybdenum wire mesh source were realized and discussed in detail. A series of characteristic morphologies of α-MoO3 nanostructures including layered nanobelts, nanoplates, and nanoflakes doping with nanocubics were fabricated via specific combustion conditions. These findings provide favorable access to the rapid and large-scale synthesis of high-performance nanostructure materials and may be widely used in the foreseeable future.

Graphical abstract

Flame vapor deposition (FVD) method provides a robust approach for mass-production of α-MoO3 nanostructures. The morphology of α-MoO3 layered nanostructures can be controllable fabricated by altering the combustion conditions. Herein, a series of characteristic morphology of α-MoO3 nanostructures including layered nanobelts, nanoplates, and nanoflakes doping with nanocubics were realized via specific combustion conditions.
