Hydrogen applications in selective catalytic reduction of NOx emissions from diesel engines

In this study, the applications of H2 in SCR of NOx have been discussed. The studies on use of H2 in SCR of NOx emissions were examined and the effects on NOx conversions were determined. Consequently, it is confirmed that H2 is a promising and alternative reductant in SCR of NOx and it has been kept as an attracting subject for many researchers.
