Synthesis and characterization of single-crystalline α-MoO3 nanofibers for enhanced Li-ion intercalation applications

Bismuth Molybdate Catalysts Prepared by Mild Hydrothermal Synthesis: Influence of pH on the Selective Oxidation of Propylene

“…39-363), and by the Raman band at 947 cm −1 assigned to the presence of Mo7O24 6− . At pH = 3-6 Mo7O24 6− [38,55] and Mo2O7 2− are the stable polymolybdate species in aqueous solution depending on the temperature [52], which agrees well with the Raman spectra of the solid phase. Bi1Mo1_pH5 exhibited a Bi/Mo bulk ratio of 1.1, which corresponds to the applied ratio and resulted in the largest surface area (32 m 2 /g, Table 1) among the different bismuth molybdates.…”

Exfoliated MoO3 nanosheets for high-capacity lithium storage

“…The stable cycle performance of MoO 3 nanosheets at high rates indicates the ultra-fast solid-state diffusion of Li + ions among the nanosheets owing to the short diffusion path length and the stable crystalloid structure. Apparently, such high-rate performance of MoO 3 nanosheets is superior to that of most of the previously reported MoO 3 -based nanomaterials, including nanofibers [29], nanobelts [22,32,33], and nanoparticles [28] obtained under similar testing conditions. It is believed that high accessible surfaces by electrolyte and abundant reactive sites of the layered MoO 3 nanosheets are the determining factors enabling such significant amount of lithium storage.…”

“…2e). To the best of our knowledge, this specific capacity value is the highest among other MoO 3 electrodes reported to date (500-900 mAh g −1 ) [19,22,[27][28][29]. As cycle number increases from the 2nd to the 30th, the capacity is steadily increasing probably because more surfaces of the electrode materials are exposed to the electrolyte.…”

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

“…First MoO3 • 2H2O is formed, which will lose water in two steps with increasing temperature [54]. In an alternative preparation route, MoO3 • 2H2O was prepared according to a literature procedure [43] and then hydrothermally treated with nitric and acetic acid, respectively at 180 °C for 48 h. The X-ray diffraction pattern of the two obtained products showed the characteristic reflections of α-MoO3 (see electronic supporting information [ESI]).…”
