Low-Temperature Reduction of NO by NH with Unity Conversion on Nanofilament MnO/Activated Semi-Coke Catalyst.

Selective catalytic reduction of nitrogen oxides with NH at low temperatures remains a crucial goal for industrial applications. However, effective catalysts operating at 70-90 °C are rarely reported, limiting SCR scenarios to high-temperature conditions. Herein, we report a unique MnO nanofilament catalyst grown on activated semi-coke synthesized via a one-step in situ hydrothermal approach, which exhibits a stable and marked 100 % conversion rate of NO to N with 100 % selectivity at 90 °C, superior to the other prepared structures (nanowires, nanorods, and nanotubes).
