Abstract
A method of forming functionalized fly ash particles includes contacting a plurality of fly ash particles with a hydroxide compound under conditions to directly bond oxygen (O) onto a surface portion of the plurality of fly ash particles. The plurality of fly ash particles having O directly bound to their surface portion are reacted with an organic alcohol or an organic acid to covalently bond hydrophobic groups in the form of condensation residue from the organic alcohol or organic acid to the O to form the plurality of functionalized fly ash particles.
