The invention discloses a high-performance copper-based denitration catalyst, which is prepared by fully grinding a copper-based catalyst CuO-SBA doped molecular sieve ZSM-5. The copper-based catalyst CuO-SBA is prepared by mixing and grinding Cu (NO3) 2.3 H2O and SBA-15 and then roasting the mixture. The copper-based catalyst is doped with the molecular sieve by adopting a solid-phase grinding method, the preparation method is simple and rapid, no solvent is used in the preparation process, and loss of active species is effectively avoided. The prepared catalyst is high in thermal stability and excellent in catalytic performance. 本发明公开了一种高性能铜基脱硝催化剂，采用铜基催化剂CuO-SBA掺杂分子筛ZSM-5充分研磨制备；铜基催化剂CuO-SBA以Cu（NO3）2·3H2O与SBA-15混合研磨后焙烧制备。本发明采用固相研磨法进行铜基催化剂掺杂分子筛，制备方法简单快捷，制备过程不使用溶剂，以有效避免活性物种的流失。制备所得催化剂的热稳定性高、催化性能优异。
