For high-temperature gas-phase reactions in the presence of steam such as the selective catalytic conversion of NOx from mobile sources, the deactivation of catalysts often occur because of their poor hydrothermal stability. Herein, we successfully prepared a high-silica Cu/ZSM-5-PAD catalyst based on an effectively induced polymer (polyacrylamide) assisted deposition (PAD) strategy. The obtained catalyst exhibited excellent catalytic performance for NH3-SCR in terms of activity, anti-hydrothermal aging and poison-resistant abilities. This excellent catalytic performance could be correlated with the encapsulation and confinement dispersion of Cu-based active species within the ZSM-5 molecular sieve channels, which dramatically optimized the catalytic properties and structural stability of the solid.
