Ultrathin MoO2 nanosheets for superior lithium storage

Carbon-coated MoO2 dispersed in three-dimensional graphene aerogel for lithium-ion battery

“…In order to overcome this problem, MoO 2 with different morphology have been synthesized, such as MoO 2 nanospheres, [13] ordered mesoporous MoO 2 , [3] tremella-like MoO 2 , [11] MoO 2 nanoparticles, [12] MoO 2 nanofibers [14] and ultrafine MoO 2 nanosheets. [15] Besides, carbonaceous materials such as amorphous carbon, [13,16] carbon nanotubes (CNT) [17,18] and graphene [19][20][21] have been used to incorporate with MoO 2 . Among these carbon materials, the amorhous carbon with good conductivity can improve the conductivity of MoO 2 .…”

Ultrathin MoO2 nanosheets with good thermal stability and high conductivity

“…In order to address this problem, it is urgent to develop a new material with a good stability and high conductivity. MoO 2 is a wide-band gap semiconductor with metallic electronic property, which has a wide applications in field emission, 21,22 supercapacitors, 23,24 lithium ion batteries, 25,26 cataly, 27,28 biosensing, 29 etc. Up to now, all kinds of MoO 2 and its composite nanostructure such as nanowire, 22 nanorod, 23,24 nanostar, 21 nanosphere, 25 nanoparticle, 27,29 MoS 2 /MoO 2 plate, 30 and MoO 2 /C nanosheet have been fabricated.…”

What's more, serious studies on thermal stability and conductivity on ultrathin MoO 2 are still lacking.…”

“…It has proved that MoO 2 and its composite is a promising anode material in lithium ion batteries, 26,33 which draw our attention to the electrical conductivity on the monodispersity of ultrathin 2D MoO 2 . The conductivities were investigated through individual MoO 2 nanosheets.…”

A general approach towards carbon nanotube and iron oxide coaxial architecture and its lithium storage capability

“…Firstly, Fe 2 O 3 nanocrystals have a fine size about 5e10 nm, so that the solid transport length of both electron and Li ion is greatly reduced. Secondly, the CNT network on which Fe 2 O 3 are anchored serves as a flexible electronic path for rapid charge transfer and thus leads to reduced electrode reaction resistance [39]. In addition, the one-dimensional coaxial cables entangle to porous framework that facilities Li ion diffusion.…”
