Abstract: The emission of nitrogen oxides (NOx) from stationary sources，primarily from power stations，industrial heaters and cogeneration plants，represents a major environmental problem. This paper intends to give a general review over the advances in non-thermal plasma assisted selective catalytic reduction (SCR) of NOx with lower hydrocarbon compounds. In the last decade，the non-thermal plasma induced SCR of nitrogen oxide with low hydrocarbon compounds has received much attention. The different hydrocarbons (≤C3) used in the research are discussed. As we know，methane is more difficultly activated than non-methane hydrocarbons，such as ethylene and propylene etc. The reduction mechanism is also discussed. In addition，aiming at the difficulties existed，the direction for future research is prospected.
