Thermoexfoliated graphite — transitional metal nanocomposites
Composite materials (CM) have been obtained by chemical deposition of metal on graphite surface. It has been shown that TEG-nanoscaled transition metal CM can be prepared both by long-term salt decomposition on TEG surface and simultaneous reduction in hydrogen flow and by preliminary salt decomposi...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Composite materials (CM) have been obtained by chemical deposition of metal on graphite surface. It has been shown that TEG-nanoscaled transition metal CM can be prepared both by long-term salt decomposition on TEG surface and simultaneous reduction in hydrogen flow and by preliminary salt decomposition to metal oxide by thermal shock at high temperature. The application of "thermal shock" regime at the salt decomposition stage and metal oxide formation has been shown to result in metal particle formation possessing the size ten fold smaller than that in a case of "direct reduction". The metal particle size distribution obeys Gauss law and practically does not depend on metal component content. |
