Heavy metal challenge in NH3-SCR DeNOx catalysts: Poisoning deactivation mechanisms and enhanced resistance strategies

Ammonia selective catalytic reduction (NH3-SCR) is the most widely used technology in the field of industrial flue gas denitrification. However, the presence of heavy metals in flue gas can seriously affect the performance of SCR catalysts, leading to their deactivation or even failure. Therefore, i...
