Abstract
Disclosed is a carbon molecular sieve material. It is prepared by a method comprising the step of adsorbing a mixture of an aqueous carbohydrate solution and an acid or a polymer precursor into pores of an inorganic molecular sieve material; drying and polymerizing the adsorbates; re-adsorbing a mixture of an aqueous carbohydrate solution and an acid or a polymer precursor onto the resultant mixture obtained in the previous steps, and drying and polymerizing the adsorbates; carbonizing the adsorbates through thermal decomposition; and removing the framework of the inorganic molecular sieve from the carbonized adsorbates by use of a fluoric acid or a sodium hydroxide solution. With uniformity in pore size and regularity in structure, the carbon molecular sieve is suitable for use in catalysts, adsorbents, supports, sensors, electrodes, etc.
