Abstract
A surface-modified activated carbon is provided to reduce the amount of free fine carbon particles among the activated carbon. By surface-modifying the activated carbon with a layer, the activated carbon can have increased mechanical strength and the fine carbon particles among the activated carbon can be fastened to the layer. Therefore, the layer allows for the level of free fine carbon particles among the activated carbon to be reduced. Surface-modified activated carbon can be used in smoking articles so as to allow for adsorption by the activated carbon with reduced free fine carbon particles in the smoking article and the smoke produced.
