Patent ID: 7488699

Claim:
A method for preparing a hollow mesoporous carbon electrode-catalyst, which comprises the following steps: a) preparing a micro emulsion, which comprises mixing water, a water-insoluble oil, and a surfactant, wherein the volume of said oil is less than the volume of said water; b) preparing a molecular sieve template for synthesizing a hollow mesoporous carbon material, which comprises preparing an acidic aqueous solution containing a silicon oxide and an alkali metal source dissolved therein, mixing said micro emulsion with said acidic aqueous solution, heating the resulting mixture at 50° C. to 200° C. for a sufficient period of time to form a molecular sieve, and calcining said molecular sieve to obtain a surfactant-free molecular sieve template; c) introducing a carbon precursor into said molecular sieve template, which comprises impregnating said molecular sieve template with a carbon precursor solution; d) heating said molecular sieve template impregnated with said carbon precursor in an inert atmosphere to carbonize said carbon precursor contained therein; e) removing said molecular sieve template to obtain a hollow mesoporous carbon material; and f) depositing a catalyst metal on said hollow mesoporous carbon material.
