During the photoreaction, we found that both NO2 and N2 disappear and additional NO appears at the same time. A reaction pathway is proposed and verified by the results of an online chemiluminesce NOx analyzer, GC-TCD, and in situ DRIFT monitoring of the reactants and products in mixtures. The collected data indicates that NO2?+?? N2?¡÷?2NO is an overall reaction of this photocatalytic reaction over a WO3 photocatalyst. ? 2017, Springer Science+Business Media B.V.Nitrogen dioxide (NO2)Nitrogen monoxide (NO)PhotocatalysisReaction pathwayTungsten trioxide (WO3)Visualizing reaction pathway for the photo-transformation of NO2 and N2 into NO over WO3 photocatalystjournal article10.1007/s11164-017-3065-62-s2.0-85025433235https://www.scopus.com/inward/record.uri?eid=2-s2.0-85025433235&doi=10.1007%2fs11164-017-3065-6&partnerID=40&md5=cef481157db10b3b4cb251d9c889212c
