The application of modified layered double hydroxides in selective catalytic reduction of nitrogen oxides by ammonia (NH₃-SCR)

Selective catalytic reduction with ammonia (NH₃-SCR) is very efficient DeNOx technique. According to some problems with the commercial catalyst, novel one should be prepared. Hydrotalcites are potential precursors of the new catalysts of NH₃-SCR. In this paper, several attempts to apply these materials in NH₃-SCR are presented.
