Reduced graphene oxide is a very attractive material for sensor applications. It exhibits high conductivity at room temperature and specific surface area. Since it can be produced in many ways, its properties influenced by the fabrication method. In this paper, we investigated influence of graphite precursors (flake, scalar synthetic) on size reduced oxide. We have shown that precursor determin...

Microwave-assisted heating method is used to treat graphite oxide (GO), pyrolytic graphene oxide (PGO) and hydrogen-reduced pyrolytic graphene oxide (HPGO). Pure or doped graphene are prepared in the time of minutes and a thermal deoxygenization reduction mechanism is proposed to understand their microwave adsorption behaviors. These carbon materials are excellent catalysts in the reduction of ...

Methods for obtaining efficient sorption materials based on highly porous melamine and polyurethane matrices modified with reduced graphene oxide were developed.

Reduced oxides (rGOs) synthesized from suspensions using potassium hydroxide, ascorbic acid or hydrazine hydrate. Composites obta...

We have developed a green method to reduce graphene oxide via a UV-irradiated photoreduction process in which H(3)PW(12)O(40) was used as photocatalyst. Moreover, H(3)PW(12)O(40) can adsorb on the reduced graphene oxide as anionic stabilizer and lead to water dispersible graphene sheets.

Morphology and size of platinum nanoparticles are a crucial factor in improving their catalytic activity and stability. Here, we firstly report the synthesis of high loading Pt nanoparticles on polydopamine reduced Graphene. The loading concentration of Pt (nanoparticles) NPs on Graphene can be adjusted in the range of 60-70%.With the insertion of polydopamine between Graphene oxide sheets, sta...

With the rapid development of graphene synthesis and functionalization approaches, graphene and its related derivatives have shown great potential in many applications in material science, including biomedical applications.
