“…Recently, electrodeposition has been proposed as an alternative route for the production of MoO 2 , and a number of nanostructures, such as nanowires [19,20], and nanofibers [21], have been synthesized. The composite electrodes based on electrochemically synthesized MoO 2 nanowires possess long-term cycle stability and a specific capacitance as high as 597 Fg −1 [19].…”

“…The composite electrodes based on electrochemically synthesized MoO 2 nanowires possess long-term cycle stability and a specific capacitance as high as 597 Fg −1 [19]. Electrolytic MoO 2 nanowires offer an alternative substitute for manufacturing Mo-based emitters [20] and can be used as a precursor [21] for the production of Mo nanowires. However, to our knowledge, the MoO 2 film, obtained by electrodeposition, has not yet been characterized for its photoelectrochemical performance.…”

Thin MoO 2 films were electrodeposited on a selenium pre-deposited SnO 2 |glass plate. The photoelectrochemical properties of MoO 2 films were investigated in 0.1 M Na 2 SO 4 solution by the ultraviolet-visible spectrophotometry, linear sweep voltammetry, and altering current impedance measurement techniques. It was found that under illumination with the incident light of λ=366 nm, the photo response of the MoO 2 |SnO 2 |glass electrode resulted from the MoO 2 layer, while the SnO 2 layer served as a sink for photogenerated charge carriers. The MoO 2 film exhibited ntype conductivity. A schematic band structure diagram of MoO 2 in 0.1 M Na 2 SO 4 solution was constructed. The flat band potential (E fb ), the donor concentration (N D ), the photogeneration current efficiency depended on MoO 2 film thickness. The [Fe(CN) 6 ] 4−/3− redox PEC cell with MoO 2 | SnO 2 |glass plate as a photoanode was constructed. Power output characteristics such as the open circuit voltage (V OC ), short circuit current (I SC ), the fill factor (FF), and the lightto-electrical conversion efficiency (η) were determined. The maximum light-to-electrical conversion efficiency exhibited by the PEC cell was 0.94 %.

“…Porous and hollow spherical MoO 2 were synthesized by a hydrothermal reaction [7,12]. The one dimensional nanostructures of MoO 2 can be synthesized by carbon nanotubes templated growth [13], thermal evaporation [14][15][16][17] and some other methods [18]. For example: Zhou et al [14] prepared large-scale MoO 2 nanowire arrays by thermal evaporation of Mo boat.…”

“…For instance, this material can be used in gas sensors, catalysis, smart windows, lithium microbatteries (Dieterle, M. 2001). MoO 2 has potential applications as a cathode material in the area of microbatteries; field emission, and also catalysis (Jun, Z. et al 2003;Wang F. & Lu B. 2009;Mikhailova, D. et al 2011).…”
