Abstract PURPOSE:To obtain a CO collecting agent having excellent CO collecting performance by exchanging Na of ZSM-5 type zeolite wherein alumina per silica by molar ratio is small for Cu ion and heating the zeolite under CO atmosphere. CONSTITUTION:Na of ZSM-5 type zeolite wherein alumina per silica by molar ratio is <=19 is exchanged for Cu ion and thereafter the zeolite is heated at 150-500 deg.C under the CO atmosphere to obtain copper ( I ) type zeolite. The zeolite has more excellent collecting performance for CO than conventional performance.
