Granular mesoporous silica and preparation method thereof

Abstract

Disclosed are granular mesoporous silica and a preparation method thereof. The preparation method includes preparing powdered silica containing a structure derivative to form mesopores; preparing a molded precursor including the powdered silica and an inorganic binder or an organic binder; preparing a granular molded article having a predetermined shape by extruding or injection-molding the molded precursor; and removing the structure derivative by calcinating the granular molded article. The granular mesoporous silica represents superior pore characteristics and is used as an adsorbent capable of effectively removing pollutants in water treatment and air pollution treatment.
