The selective catalytic oxidation of NH3
(NH3
-SCO) into N2 and H2O is an efficient
technology for NH3 abatement in diesel vehicles. However, the catalysts dedicated to NH3
-SCO
are still under development. One of the groups of such catalysts constituted transition metal-based
catalysts, including hydrotalcite-derived mixed metal oxides. This class of materials is characterized
by tailored composition, homogenously dispersed mixed metal oxides, exhibiting high specific
surface area and thermal stability. Thus, firstly, we give a short introduction to the structure and
composition of hydrotalcite-like materials and their applications in NH3
-SCO. Secondly, an overview
of other transition metal-based catalysts reported in the literature is given, following a comparison of
both groups. The challenges in NH3
-SCO applications are provided, while the reaction mechanisms
are discussed for particular systems
