Remarkable N-selectivity enhancement of NH-SCR over HPMo modified MnCo-BTC@SiO catalyst.

In this work, the phosphomolybdate (HPMo) modification strategy was applied to improve the N selectivity of MnCo-BTC@SiO catalyst for the selective catalytic reduction of NO, and further, the mechanism of HPMo modification on enhanced catalytic performance was explored. Among MnCo-BTC@SiO-x catalysts with different HPMo concentrations, MnCo-BTC@SiO-0.75 catalyst exhibited not only the highest NH-SCR performance (∼95% at 200-300°C) but also the best N selectivity (exceed 80% at 100-300°C) due to the appropriate redox capacity, greater surface acidity.

Low-temperature NH-SCR performance of a novel Chlorella@Mn composite denitrification catalyst.

The synthesis process of conventional Mn-based denitrification catalysts is relatively complex and expensive. In this paper, a resource application of chlorella was proposed, and a Chlorella@Mn composite denitrification catalyst was innovatively synthesized by electrostatic interaction. The Chlorella@Mn composite denitrification catalyst prepared under the optimal conditions (0.
