Method of producing a composite, more precisely a nanoporous body and a nanoporous body produced thereby

摘要

The present invention is related to a method of producing a nanoporous body containing nanodiamonds and having a desired shape, comprising the steps of: forming an intermediate body having the desired shape of nanodiamond particles having a maximum size of 10 nm, exposing said body to a gaseous hydrocarbon or a mixture of hydrocarbons at a temperature exceeding the decomposition temperature for the hydrocarbon or the hydrocarbons. In accordance with the invention the intermediate body is formed with a porosity of 50-80 vol. %, and during the heat treatment of the intermediate body with hydrocarbon or hydrocarbons, the mass of the body is increased by 50% at the most. The present invention also relates to a nanoporous body produced by the method and to uses of such a body.
