Controllable synthesis of MoO3-deposited TiO2 nanotubes with enhanced lithium-ion intercalation performance

Rapid flame synthesis of internal Mo6+ doped TiO2 nanocrystals in situ decorated with highly dispersed MoO3 clusters for lithium ion storage

“…Moreover, the first scan on the negative-current side have a broad reduction peak in the range of 0 to 1.25 V. Compared with the following scans, these irreversible peaks are mainly attributed to the formed solid electrolyte interphase (SEI) films. 20,21,36 These observed peaks further confirmed that the electrochemical reaction takes place in a multistage process with active TiO 2 and MoO 3 components.

“…Recently, oxides nanocrystals with high electrochemical acitivity (i.e., SnO 2 : ~ 790 mA h g -1 , MoO 3 : ~ 1111 mA h g -1 ) have coupled with stable TiO 2 for achieving superior performance. [20][21][22] Yu et al have demonstrated that 5 at.% Sn modified TiO 2 nanotube exhibited a highly specific capacity of 386 mA h g -1 at 0.1 C after 50 cycles. 23 Similar stable capacity of 485 mA h g -1 at 50 mA g -1 is delivered for SnO 2 /TiO 2 .…”

Lithium storage study on MoO3-grafted TiO2 nanotube arrays

“…3. As the deposited layer of nanoflakes thickens with increasing reaction time so capacity decreases, consistent with literature (Guan et al 2014a;Zhu et al 2015). The Li insertion and extraction plateau can be observed till 6 h time duration which indicates incorporation of TNAs, but length of plateau decreases with increase in time.…”

Nanoporous TiO2/Co3O4 Composite as an Anode Material for Lithium-Ion Batteries

“…In addition, the formation of the composites can efficiently alleviate the mechanical stress and prevent from the aggregation of the active domains [21]. A variety of composites built by hybridizing TiO 2 with other metal oxides have been reported in previous works, such as TiO 2 -C/MnO 2 nanowire arrays, TiO 2 /MoO 3 nanotubes, and TiO 2 /Co 3 O 4 nanobelt 5 arrays [22][23][24]. Especially, Co 3 O 4 with the advantages of high theoretical capacity (890 mA h g -1 ) and good stability has been demonstrated to be an effectively addressed metal oxide that can modify the reversible capacity, cyclability, and rate capability of TiO 2 [24].…”
