Improving the hydrothermal stability of Al-rich Cu-SSZ-13 zeolite via Pr-ion modification

Al-rich (Si/Al = 4-6) Cu-SSZ-13 has been recognized as one of the potential catalysts to replace the commercial Cu-SSZ-13 (Si/Al = 10-12) towards ammonia-assisted selective catalytic reduction (NH -SCR). However, poor hydrothermal stability is a great obstacle for Al-rich zeolites to meet the cataly...
