In recent years, selective catalytic reduction (SCR) with NH 3 technology has been
extensively applied in the removal of nitrogen oxide (NO x) from diesel exhaust due to its …

NH 3-SCR was one of the most promising deNO x technologies and it has been widely
applied in industrial NO x reduction. However, with the further development of energy …

The poisoning of sulfur oxides and alkali metals emitted from diesel exhaust to active sites of
copper ion-exchanged chabazite (Cu-CHA) catalysts is still present and remains a …

Cu-ZSM-5 zeolites exhibit promising NH3-SCR activity in a wide temperature window. The
current challenges in preparing Cu-ZSM-5 are reducing the cost and simplifying the …

The continuously updated after-treatment system of diesel engines drives the selective
catalytic reduction of ammonia (NH3-SCR) catalysts to withstand hydrothermal stability at …

The presence of alkali metals in flue gas is still an obstacle to the practical application of
catalysts for selective catalytic reduction (SCR) of NO x by NH3. Polymeric vanadyl species …

In this study, a series of K species or/and SO 2 poisoned Mn-Ce doped CuX (MCCX)
catalysts were prepared from waste blast furnace slag (BFS), and the influence mechanism …

A series of Cu-exchanged zeolite NaX (derived from blast furnace slag) catalysts were
synthesized by an ion-exchanged method. The low-temperature catalytic activity and SO2 …

Selective catalytic reduction of NO x from mobile source over Cu-SAPO-34 catalysts always
suffer from sulfur poisoning in practical applications. The pore blockage and loss of active …

Environmentally benign CeO2–WO3/TiO2 catalysts are promising alternatives to commercial
toxic V2O5–WO3/TiO2 for controlling NOx emission via selective catalytic reduction (SCR) …
