Abstract: Adsorption of NH3 on the Mn/palygorskite catalyst prepared by heterogeneous co-precipitation occurs mainly on the palygorskite support. Loading of manganese oxides does not promote NH3 adsorption on the catalysts but increases the activation of adsorbed NH3.

Key words: palygorskite, manganese oxide, low-temperature selective catalytic reduction, ammonia adsorption-desorption
