Dataset Information

Tunable preparation of highly dispersed Ni _x Mn-LDO catalysts derived from Ni _x Mn-LDHs precursors and application in low-temperature NH₃-SCR reactions.

ABSTRACT: A series of Ni _x Mn bimixed metal oxides (Ni _x Mn-LDO) were prepared via calcining Ni _x Mn layered double hydroxides (Ni _x Mn-LDHs) precursors at 400 °C and applied as catalysts in the selective catalytic reduction (SCR) of NO _x with NH₃. The DeNO _x performance of catalysts was optimized by adjusting the Ni/Mn molar ratios of Ni _x Mn-LDO precursors, in which Ni₅Mn-LDO exhibited above 90% NO _x conversion and N₂ selectivity at a temperature zone of 180-360 °C. Besides, Ni₅Mn-LDO possessed considerable SO₂ & H₂O resistance and outstanding stability. Multiple characterization tech
