Abatement of NO x emissions by selective catalytic reduction (SCR) on vanadia‐based heterogeneous catalysts is promoted by structural effects caused by tungsten oxide. The mechanism is identified by J. Z. Hu, Y. Wang, I. E. Wachs, and co‐workers in their Research Article on page 12609 ff. The SCR is shown to proceed via a two‐site mechanism over adjacent vanadia sites. The use of tungsten oxide results in vanadia oligomerization which enhances NO x abatement.
