Abstract

Nitrogen oxides (NOx) are the main components of air pollutants.Selective catalytic reduction method is wildly applied to control the nitrogen oxides (NOx) emission in flue gas with V2O5 own to high denitrification and wide usage.But it also has the disadvantages of low low-temperature activity and high energy consumption.Photo-catalytic selective reduction of NOx is an environmentally friendly treatment process for purifying flue gas with TiO2,which utilizes light to convert NOx into N2 under middle and low temperature.The advantages of high low-temperature activity and low energy consumption make it have broad application prospects.The recent advances in photo-catalytic reduction of NOx and the ways improve the efficiency were reviewed.And some suggestions on the current development direction of photo-catalytic selective reduction NOx technology were put forward.
