Synthesis of metastable h-MoO3 by simple chemical precipitation

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

“…Figure 3(a) is the FT-IR spectrum of h-MoO 3 hexagonal prisms, which is similar to the reported reference. [16] The bands at 973 and 717 cm ¡1 are attributed to stretching mode of MoHO double bond. The splitting peaks at 590 and 515 cm ¡1 are assigned as OÀMoÀO stretching and bending modes with different MoÀO bond lengths.…”

“…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. Zheng and co-workers [16] has synthesised h-MoO 3 rods through chemical precipitation, hydrothermal treatment and calcination steps. Xie and co-workers [8] has prepared h-MoO 3 nanobelts by a hydrothermal route.…”

Catalytic oxidative desulfurization of diesel fuel utilizing a polymolybdate alumina supported catalyst: characterization, catalytic activity and mechanistic study

“…8. From the IR spectrums of TBHP and surface Fe/MoO 3 /Al 2 O 3 catalyst after 0 and 5 min oxidation, the broad band at 3333 cm -1 and 1638 cm -1 were observed, which were assigned to-OH stretching and bending vibration band of H-O-H, respectively [16,17]. The presence of the water molecule and OH group are due to presence of water in TBHP.…”

In-situ phase transition to form porous h-MoO3@C nanofibers with high stability for Li+/Na+ storage

“…Compared to graphite anodes, they have high theoretical capacity, such as MoO 3 (1,117 mA h g −1 ) [29,30], including the well-known thermodynamically stable normal phase α-MoO 3 [31,32], and metastable phase h-MoO 3 [33,34]. As reported, metastable structures often demonstrate new or enhanced properties compared to their thermodynamically stable forms.…”
