Abstract
The present invention relates to a catalyst for the catalytic reduction of nitrogen oxides in the presence of hydrogen (H2-SCR) comprising an active phase comprising platinum, tungsten and sodium, and a support comprising at least titanium dioxide, characterized in that: - the platinum content is between 0.01 and 10% by weight of element platinum relative to the total weight of the catalyst; - the tungsten content is between 1 and 30% by weight of element tungsten relative to the total weight of the catalyst; - the sodium content is between 0.5 and 5% by weight of element sodium relative to the total weight of the catalyst.
