1. A process for the preparation of a microporous carbon material from pyrolysis of microspheres of a poly (vinylidene chloride) copolymer that have been chemically treated with alkali or alkaline earth metal hydroxides or alkoxides, comprising:
carrying out a first heating of the microspheres at a rate of 0.25° C./min to 1.75° C./min to a temperature of between 700° C. to 1200° C., and a second heating of the microspheres for 300 min to 1200 min to a temperature of between 700° C. to 1200° C.; and
carrying out a cooling of the microspheres at a rate of 0.25° C./min to 1.75° C./min;
wherein the resulting microporous carbon materials have a carbon content in the microsphere shell of 80% to 97% by mass, and wherein the microporous carbon material has oxygen in the microsphere shell.
