Abstract

A method of making a filter material for producing potable water comprises providing activated carbon particles, depositing one or more nanofilament precursors at least partially onto the surface of the activated carbon particles, agitating the activated carbon particles and deposited nanofilament precursors in the presence of carbonaceous vapor, and heating the activated carbon particles and the deposited nanofilament precursors in the presence of carbonaceous vapor at a temperature and time sufficient to produce the filter material comprising activated carbon particles having carbon nanofilaments on the surface of the particles.
