A porous electrochemical electrode is made up of a solid cellular material provided in the form of a semi-graphitized carbon monolith comprising a hierarchized porous network free of mesopores and including macropores with a mean dimension dof 1 &#x3bc;m to 100 &#x3bc;m, and micropores with a mean dimension dof 0.5 nm to 2 nm, said macropores and micropores being interconnected. In said electrode, the macropores contain at least one electroactive species in direct contact with the semi-graphitized carbon that makes up the surface of the macropores. The invention also relates to a method for preparing such an electrode as well as to the use thereof as a biosensor or for manufacturing a biopile.

Enzymatic modifications of a cellular monolithic carbon and uses thereof

A carbon or ceramic monolithic materials with an M2 (macroporous/microporous) hierarchised porous structure is provided as well as method for preparing said materials using a macro/meso/microporous silica cavity. Such materials may be used, in particular for the production of hydrogen purifiers, supercapacitors or electrodes, or else for carrying out catalysed chemical reactions in a heterogeneous phase.

Method for preparing a cellular carbon monolith comprising a hierarchised porous network

A method is provided for storing hydrogen in a macroporous monolithic material by the heterogeneous nucleation of a metal hydride. A composite material is provided for storing hydrogen directly obtained by the method. A method is also provided for employing the material for the production of dihydrogen, as well as a method for producing dihydrogen using such a composite material.
