The issue of deactivation and low-temperature SCR activity of  V2O5-based catalysts is addressed by reformulating the catalyst with deposition of iron-erbium  mixed vanadate on TiO2-WO3-SiO2 support. Varying the Fe/Er ratio in the vanadate it is possible to control catalytic activity and thermal stabilty.
