METHOD OF PREPARING POROUS CARBON

摘要

The invention provides a method of preparing porous carbon with adsorbent properties for use in smoke filtration, the method comprising: pre-treating a starting material with an alkali solution; removing the alkali solution from the pre-treated material; and then activating the pre-treated material, wherein the starting material is a carbon precursor or a microporous carbon material. Preferably, the alkah solution is removed before the activation step. The invention also provides a porous carbon with micropores and mesopores, and uses thereof.
