專利摘要

This present invention provides a microporous carbon nanospheres, method for synthesizing and activating thereof, the method comprising: adding and mixing well deionized water, absolute ethanol, triblock copolymer, ammonia solution, resorcinol and formaldehyde solution; separating solid and liquid of the mixture solution, then drying the separated solid substrate to have a dried solid substrate; sintering the dried solid substrate surrounding by nitrogen twice and collecting microporous carbon nanospheres after cooling down. Further sintering to activate these microporous carbon nanospheres surrounding by carbon dioxide, and collecting activated microporous carbon nanospheres after cooling down. Microporous carbon nanospheres and activated microporous carbon nanospheres synthesized by this present invention have spherical structure, small size and high the specific surface area, and the process is simplified, cost-effective and environment-friendly.
