An adsorbent for exhaust gas, produced by mixing an Fe-ZSM-5 containing base material obtained by Fe ion exchange of ZSM-5 having an Si/Al2O3 molar ratio of 28(the number of moles of Si : the number of moles of Al2O3 = 28:1) with an additive containing at least one member selected from among Y-zeolite having an Si/Al2O3 molar ratio of 250, mordenite having an Si/Al2O3 molar ratio of 200, and β-zeolite having an Si/Al2O3 molar ratio of 400. The adsorbent can effectively adsorb both hydrocarbons and nitrogen oxides simultaneously. |
