Risk Of Offensive/Incorrect Content: New catalysts remove NOx pollutants at lower temperatures

(Tokyo Metropolitan University) Scientists from Tokyo Metropolitan University have developed a low-temperature catalyst for removing NOx gas from industrial exhaust using ammonia. Composed of bulk 'defective' vanadium oxide instead of vanadium oxides supported on titanium oxide like in commercial catalysts, the catalyst works at lower temperatures (< 150 degrees Celsius) with much higher efficiency. The team demonstrated a clear improvement in performance, and identified the reaction mechanisms responsible for the difference.
