DRIFTS and mass spectrometry were employed to study isocyanate formation and reactivity. DRIFTS demonstrated that Ba-NCO is a critical intermediate during reduction of Ba nitrate with CO. Simultaneous MS results during isocyanate reaction with different gas species suggested the existence of two pathways for N₂formation during NOx reduction.
