摘要:A highly practical SCR catalyst excellent in NOpurification performance isprovided. The SCR catalyst includes a blend of an aluminosilicate molecular sieve that hassupported thereon copper as an extra-framework metal and that has a CHA framework,and a silicoaluminophosphate molecular sieve that has a CHA framework, and is adaptedto perform selective catalytic reduction of NO. In the SCR catalyst, the

silicoaluminophosphate molecular sieve and the aluminosilicate molecular sieve containsilicoaluminophosphate and aluminosilicate, respectively, in a molar ratio ofsilicoaluminophosphate:aluminosilicate of 0.1:1.0 to 0.4:1.0.
