One-pot Synthesis of Phosphorus-modified AEI Zeolites Derived by the Dual-template Method as a Durable Catalyst with Enhanced Thermal/Hydrothermal Stability for Selective Catalytic Reduction of NOx by NH3

Phosphorus-modified AEI zeolites, synthesized by the dual template method using a mixture of N,N-diethyl-2,6-dimethylpiperidinium and tetraethyl phosphonium cations, exhibited excellent thermal/hydrothermal stability in the selective catalytic reduction of NOx by NH3.
