Morphology-Controlled Flame Synthesis of Single, Branched, and Flower-like α-MoO₃Nanobelt Arrays

Abstract

We report an atmospheric, catalyst-free, rapid flame synthesis technique for growing single, branched, and flower-like α-MoO(3) nanobelt arrays on diverse substrates. The growth rate, morphology, and surface coverage density of the α-MoO(3) nanobelts were controlled by varying the flame equivalence ratio, the source temperature, the growth substrate temperature, and the material and morphology of the growth substrate. This flame synthesis technique is a promising, alternative way to synthesize one-dimensional metal oxide nanostructures in general.

Photoelectrode for water splitting: Materials, fabrication and characterization

“…MoO 3 nanobelt (Fig. 10b) and WO 3 nanorod film have been fabricated in this way and the derived WO 3 /BiVO 4 photoanode delivers a photocurrent as high as 3.1 mA cm −2 [89,92]. Molecular beam epitaxy (MBE) is another advanced film fabrication method in preparing film with high quality crystal.…”

Metastableh-MoO3and stableα-MoO3microstructures: controllable synthesis, growth mechanism and their enhanced photocatalytic activity

“…[7] Hexagonal h-MoO 3 , constructed of the zigzag chains of [MoO 6 ] octahedral as the building blocks interlinked through the cis-position, possess large one-dimensional (1D) tunnels along [001] direction. [8] Over the past years, various methods, including chemical vapour deposition, thermal evaporation, rapid flame and hydrothermal technology, etc., have been applied to prepare a-MoO 3 with special morphologies, such as nanorods, [9] lamellar pattern, [7] nanobelt arrays, [10] nanobelts, [6,11À13] nanotubes, [14] hollow spheres, [15] and so forth. However, the synthesis of metastable compound is usually more difficult, resulting in that the numbers of successful efforts to synthesise h-MoO 3 have been very limited and thus limit its applications.…”

A facile hydrothermal method for the fabrication of one-dimensional MoO3 nanobelts

“…One-dimensional metal oxide nanostructures have always drawn considerable attention for their attractive physical and chemical properties [1,2]. Among various metal oxides, onedimensional MoO 3 including nanobelts [3], nanotubes [4] and nanorods [5] attracts much attention owing to its wide applications as catalysts [6], photoconductive devices [7], battery electrodes [3] and supercapacitors [8].…”
