DOI: 10.1016/j.cattod.2019.06.074
Abstract: Abstract Cu/SSZ-13 has considered being a good candidate for NH3-SCR catalysts. However, in real world, Cu/SSZ-13 inevitably expose to alkali metals deposit and hydrothermal aging, and hence, the role of alkali ions (Na+ and K+)… read more here.

DOI: 10.1016/j.micromeso.2021.111060
Abstract: Abstract Cu/SSZ-39 is an alternative highly effective catalyst for selective catalytic reduction of NOx compounds in Diesel exhaust besides Cu/SSZ-13. The hydrothermal stability of Cu/SSZ-39 exhibits an obvious dependency on Cu contents. Further experiment evidence… read more here.
