Removal of Formaldehyde from the Indoor Environment Using Porous Carbons and Silicas

Abstract

Formaldehyde, carcinogenic for humans, is a common indoor air pollutant emitting from furniture coatings and flooring materials. Porous carbon and silica materials have applications in the removal of formaldehyde because of their large specific surface areas, obedience to surface modification for enhanced adsorption of pollutants, high chemical and mechanical stabilities, and reusability. This work briefly summarized available porous carbon and silica materials for the removal of formaldehyde from the indoor environment.
