Краткое описание проекта

Nanostructural materials are new direction of creation and development of functional materials with unique properties, which cannot be formed spontaneously in usual natural conditions. It opens new possibilities in the development of electronics, optics, catalysis, biotechnology, medicine. Materials on the graphene base attracts now a great attention because of a great specific surface, unique electrical, thermal and mechanical properties for the creation of the electrodes for supercapacitors, gas sensors, as catalyst supports and absorbents of different gases. But the absence of techniques of synthesis of required big quantities of graphene materials restricts greatly their use. For this reason, the development of effective methods of synthesis of nanosized metal oxides with graphene and nanosized metal oxides and reduced graphene oxide, full characterization of their chemical properties, phase contents, study of their dispersion a dependence of synthesis conditions and thermal treatment and development of composites on their base is a very attractive task.
In connection with the aforesaid, the main purpose of the project is the development of synthesis methods of graphene-like nanostructures and fabrication of the related composites aimed at obtaining new gas absorbents, catalysts supports, and supercapacitors.
To reach the goal of the Project the following tasks will be solved:
1. Graphite oxide and related highly dispersed carbon nanomaterials will be synthesized using modified Hummers method and characterized.
2. Graphene-like nanostructures will be synthesized by the reduction of graphite and graphene oxides and catalytic pyrolysis of hydrocarbons and characterized.
3. Metal-graphene structures will be obtained and their functional properties will be studied.
4. New composite materials will be fabricated; their properties will be studied.
5. The perspectives of the use of the graphene-like nanostructures as gas absorbents, catalyst supports and supercapasitors will be explored.
State of Research in Institute of Chemistry:
● work experience gained and synthesis methods developed in nano-sized rare-earth and transition metal oxides as well as carbon nanomaterials.
● laboratory equipment has been built to fabricate composites based on highly dispersed carbon materials.
● properties and applications of so called 3D graphene foam have been reviewed.
Influence of the proposed Project on progress in the area.
It is known that in recent two decades a variety of nanostructured materials (thin films, particles, fibers, etc.), i.e. which are smaller than a one tenth of a micrometer in at least one dimension, has received much attention of scientists and engineers.
Nano-meter scale can impart novel properties to the matter. Due to this reason nanomaterials are employed in various fields, including medicine, electronics, aerospace, etc.
Therefore, the synthesis and study of new grapheme-like structures will have both scientific and practical importance.

Technical Approach and Methodology
Graphene nanostructures will be synthesized by the thermal or chemical reduction of graphite oxide using hydrazine as a reducing agent, or sodium borohydride, as well as by the catalytic pyrolysis of hydrocarbons on the surface of metal substrates Co, Ni or Cu. The resulting composites will be studied as gas absorbents, catalysts of organic reactions, fuel cell electrode materials, electrochemical sensors, and supercapacitors.
