Abstract:
A process for the preparation of an amorphous ruthenium oxide composite comprising:a. impregnating high surface area carbon fibers dispersed in a cellulose matrix with an aqueous solution of a ruthenium source;b. drying the matrix of ruthenium source impregnated carbon fibers at a temperature sufficient to remove water;c. heating the dried matrix of impregnated carbon fibers in a steam and oxygen atmosphere containing at least 30 weight percent water at a temperature up to about 500.degree. C. for a time sufficient to convert the ruthenium source to amorphous ruthenium oxide hydrate; andd. recovering as said composite the amorphous ruthenium oxide hydrate impregnated on high surface area carbon fibers dispersed in a cellulose matrix.
