Utilization of waste tire derived activated carbon as CO capture and photocatalyst for CO conversion.

The aims of this research were to prepare activated carbon (AC) impregnated with tetraethylenepentamine (TEPA) for use in carbon dioxide (CO) capture and to then develop the AC-TEPA sorbent with titanium dioxide (TiO) as a catalyst for photocatalytic reduction. The AC was impregnated with TEPA at three loading levels (2.5, 5, and 10% [w/w]) and then examined for its CO adsorption capacity under an ambient temperature and atmospheric pressure.
