Combination of low dimensional carbon nanostructures, possessing high electrical conductivity and specific
surface, with semiconducting nanoparticles containing transitional metals allows creation of new class of hybrid
materials with outstanding properties for different applications. Molybdenum disulfide in combinations with
carbon-based nanostructures could serve as perfect anode material for lithium storage [1,2] or catalyst [3,4].
Theoretical electrochemical capacity of carbon based materials is limited to 372 mAh/g, while the capacity of
hybrids could reach 1150 mAh/g .
In this work, we are different techniques, which allows the production of MoS2 particles on carbon
nanotube or few layer graphene support.
For the applications, where electric conductivity and high availability of sulphide nanoparticles is
significant, such as Li-ion battery materials and supercapacitors we propose to use aligned carbon nanotubes
arrays, because of its porous structure and electric connectivity. The arrays, covered with MoS2 were tested as a
Li-ion battery anode material and supercapacitor electrode, achieving high specific capacity in both cases.
Catalytic properties of MoS2 layers and nanoparticles on few layer graphene (Fig. 1) were tested on formic
acid decomposition reaction. The reaction resulted production of hydrogen with selectivity up to 50% and
organic products, such as methyl formate starting from 125°C.
