“…Such metallic compound-functionalized graphene hybrid materials were obtained mainly by the growth of nanostructured metallic compounds on the surface of graphene films by various techniques. For example, pulse laser deposition was applied to deposit V 2 O 5 film on the graphene paper surface to yield flexible energy storage devices [81]. NiO [82], TiO 2 [83][84][85], indium-gallium-zinc oxide [86] and PtNPs/MnO 2 nanowires [61] were all successfully deposited onto graphene paper surfaces for specific functionalization.…”

Graphene paper as a new form of graphene-supported nanomaterials has received worldwide attention since its first report in 2007. Due to their high flexibility, lightweight and good electrical conductivity, graphene papers have demonstrated the promising potential for crucial applications in electrochemical sensors and energy technologies among others. In this chapter, we present some examples to overview recent advances in the research and development of two-dimensional (2D) graphene papers as new materials for electrochemical sensors. The chapter covers the design, fabrication, functionalization and application evaluations of graphene papers. We first summarize the mainstream methods for fabrication of graphene papers/membranes, with the focus on chemical vapour deposition techniques and solution-processing assembly approaches. A large portion of this chapter is then devoted to the highlights of specific functionalization of graphene papers with polymer and nanoscale functional building blocks for electrochemical-sensing purposes. In terms of electrochemical-sensing applications, the emphasis is on enzyme-graphene and nanoparticle-graphene paper-based systems for the detection of glucose. We finally conclude this chapter with brief remarks and outlook.

. (2015). V 2 O 5 /mesoporous carbon composite as a cathode material for lithium-ion batteries. Electrochimica Acta, 173 172-177. V2O5/mesoporous carbon composite as a cathode material for lithiumion batteries AbstractV 2 O 5 /mesoporous carbon composite has been prepared by an ultrasonically assisted method followed by a sintering process. The as-prepared V 2 O 5 /mesoporous carbon material containing 90 wt% V 2 O 5 shows better electrochemical performance, with capacity of 163 mA h g -1 after 100 cycles at the current density of 500 mA g -1 , as well as better charge/discharge rate capability for lithium storage than V 2 O 5 nanoparticles. The improved electrochemical performance indicates that the V 2 O 5 /mesoporous carbon composite could be used as a promising cathode material for lithium ion batteries.

Vanadium pentoxide (V2O5) with a layered crystalline structure is a promising cathode material for lithium-ion batteries (LIBs) However, several problems largely restrict the battery performance of V2O5, such as small Li + diffusion coefficient, low electrical conductivity, irreversible phase transitions, and dissolution of vanadium into the electrolyte. Therefore, V2O5 exhibits poor rate capability and cycling stability. This thesis aims to improve the performance of V2O5 in regard to its electrical conductivity, lithium diffusion coefficient, and structural stability of V2O5 by using strategies, such as nanostructuring, element doping, adding carbon additives, and conductive polymer coating. .
