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

Abstract

Abstract Selective catalytic reduction with ammonia (NH 3 -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 NH 3 -SCR. In this paper, several attempts to apply these materials in NH 3 -SCR are presented.
