Self‐Assembly Approach for Synthesis of Nanotubular Molybdenum Trioxide/Titania Composite Anode for Lithium‐Ion Batteries

“…In addition, the lattice spacing (0.351 nm) and (101) SAED ring of anatase titania nanocrystallites were observed for this sample (Figure S5 b in the Supporting Information) due to the relatively higher content of titania contained therein. For the control sample of MoO 3 flakes, the HR‐TEM image (Figure S3 c in the Supporting Information) showed clear lattice spacings of 0.382, 0.341, and 0.326 nm, corresponding to the (110), (040), and (021) planes, respectively, of the typical orthorhombic molybdenum trioxide phase; and the corresponding SAED pattern (Figure S3 d in the Supporting Information) indicated that the sample was highly single‐crystalline . The structure of the present MoO 3 /TiO 2 composite is confirmed as a thin orthorhombic molybdenum trioxide layer coated onto anatase titania nanotubes.…”

“…[32,35] Thec rystalline latticesa nd diffraction rings corresponding to the anatase phase titania were not observed due to the thick MoO 3 coating layer in the composite;t his is consistent with the XRD results described above.T he elemental distribution of the MoO 3 -76 %-TiO 2 nanotube composite was determined by EDS measurements (Figure 3c), which reveal the uniform distribution of Mo,T i, and Oi nt he nanotube.I ti ss een that the molybdenum signal distributes at the outer edges of the nanotube,w hich is stronger than that of titanium; this demonstrates the MoO 3 layer was deposited onto the surface of the titania nanotube.F or the sampleM oO 3 -64 %-TiO 2 ,t he same abovementioned lattice spacings of 0.677 and 0.198 nm, corresponding to the (020) and (200) planes,r espectively,o f the orthorhombic MoO 3 phase,w ere observed in the HR-TEM image ( Figure S5 ai nt he Supporting Information). [70,71] In addition, the lattice spacing (0. the (110), (040), and (021) planes, respectively,o ft he typical orthorhombic molybdenum trioxide phase; [11,35] and the cor-responding SAED pattern ( Figure S3 di nt he Supporting Information) indicated that the sample was highly single-crystalline.

“…With ever‐increasing energy consumption, as well as more and more serious environmental issues, the search for clean, renewable, and sustainable energy resources appears to be imperative . Rechargeable lithium‐ion batteries (LIBs) are regarded as one of the most promising energy‐storage systems due to their attractive features, including high energy density, large power density, low self‐discharge rate, long cycle life, and environmental benignity, and hence, have been extensively applied in portable electronic devices, smart girds, and electric vehicles . A typical LIB system contains a cathode and an anode, as well as a separator filled with a nonaqueous electrolyte that connects the positive and negative electrodes and avoids internal short‐circuit .…”

Construction of a few-layer g-C3N4/α-MoO3 nanoneedles all-solid-state Z-scheme photocatalytic system for photocatalytic degradation

“…In the layered structure of α-MoO 3 , every layer combines with each other by the weak van der Waals interaction [32][33][34] , while the internal bonds within the layer are covalent and ionic bonds [25] . These inherent characteristics of MoO 3 made it eligible for the application in a wide range of fields, such as catalysts [35] , organic solar cells [36] , photochromic materials [37] and cathodes of Li ion batteries [38] . In the field of photocatalysis, MoO 3 is a stable, low-cost and environmental friendly but wide band-gap semiconductor [26] .…”
