DeNOx performance of Ag/Al2O3 catalyst by n-dodecane: Effect of calcination temperature

▶ The higher the catalyst calcination temperature, the higher deNOx activity has been achieved below 300 °C. ▶ A larger amount of metallic Agn clusters was formed on the catalyst surface as the catalyst calcination temperature increased. ▶ The metallic Agn clusters may be also responsible for the high deNOx performance below 300 °C as well as the ionic Ag.
