A series of MnOx-CeO2/graphene catalysts prepared by a hydrothermal method with different molar ratios of Mn/Ce active components were loaded on graphene for low-temperature SCR of NOx with NH3. Experimental results indicated that these catalysts exhibited excellent low-temperature SCR activities and strong resistance against SO2. The characterization results indicated that manganese and cerium oxides...
Mesoporous niobium nitride nanobelt arrays (Nb4N5 NBAs) are fabricated directly on Nb foils by a hydrothermal reaction in KOH, protonation treatment in HNO3, and calcination in an NH3 ambient. The morphology, composition and pore structure of the Nb4N5 NBAs are characterized in details. In addition, the mesoporous Nb4N5 NBAs electrode has good specific capacitance (37.4mFcm−2, or 124Fg−1) and delivers...
