| Outline of Final Research Achievements |
Inorganic nanoparticles coated by one, two graphene layers are very attractive for a raw material that has excellent physical and chemical properties of both the graphene and the nanoparticle. In this study, carbon-coated ceramic nanoparticles were prepared by CVD method and new functional nanocomposites were developed by using their nanoparticles. A monolithic carbon-tungsten carbide nanocomposite was prepared from carbon-coated tungsten carbide nanoparticles synthesized from tungstic acid by CVD using organic reagent. The monolith has high conductivity (106 S/m), negative thermoelectric power (-15 μV/K) and low thermal conductivity (10 W/mK), and shows a good thermoelectric property (ZT=0.08 - 0.15) as a result. A carbon monolith with good conductivity (4.2×103 S/m) and open-through nanopores was prepared by using carbon-coated alumina nanoparticles. The monolith entrapping enzymes reduces oxygens in a pH 5.0 buffer solution; i.e. it shows functionality as an enzymatic electrode.
