Hydrothermal synthesis and electrochemical properties of α-MoO3 nanobelts used as cathode materials for Li-ion batteries

Abstract

Uniform α-MoO 3 nanobelts were successfully synthesized by the hydrothermal process at 180°C for 20 h of the acidic solutions with different pH values of 0-0.75, adjusted using HCl (conc.). XRD and SEM results revealed that the pH of the precursor solutions played an important role in the phase, impurities, and morphology of the products. At the pH = 0, the perfect α-MoO 3 nanobelts with a few tens of microns long were synthesized. By the TEM characterization, orthorhombic MoO 3 has a distinctive layered structure along the [010] direction, consisting of distorted MoO 6 octahedrons connected by common corners along the [100] direction and common edges along the [001]A.

HxMoO3@C nanobelts: Green synthesis and superior lithium storage properties

“…Firstly, MoO 3 nanobelts were prepared via a facile hydrothermal approach, according to reported studies [20]. Typically, 1 g ammonium molybdate was dissolved in 30 ml deionized water under continuous stirring.…”

Systematic study on the influence of the morphology of α-MoO3 in the selective oxidation of propylene

“…The method is, however, particularly attractive for (mixed) molybdenum oxides, which have high potential as catalysts in the selective oxidation of hydrocarbons [17][18][19][20][21][22]. Various preparation routes are known for the hydrothermal synthesis of molybdenum trioxide in the shape of ribbons, rods or nanobelts [12,[23][24][25][26][27][28].…”
