A CO2 recovery apparatus according to the present invention comprises: an absorption tower comprising a CO2 absorption unit in which an exhaust gas containing CO2 and a lean solution comprising an amino group-containing compound are brought into contact with each other to allow the lean solution to absorb CO2; a regeneration tower in which CO2 contained in a rich solution is separated to regenerate the rich solution; and a purification unit in which an amino group-containing compound in a CO2-removed exhaust gas obtained by removing CO2 in the CO2 absorption unit is removed from, wherein the purification unit comprises a catalytic unit in which a photocatalyst is supported on a carrier including a gap through which air can pass, an activation member which activates the photocatalyst, and a power supply unit. The activation member is a pair of electrodes comprising a first electrode and a second electrode. |
