“…[28][29][30] Ground granulated blast furnace slag (GGBS) is a mineral resource with high recycling value. [2,5,31] GGBS is a major industrial by-product generated during the pig iron smelting process in blast furnaces. It contains significant oxide components such as CaO, MgO, SiO 2 , Al 2 O 3 , Fe 2 O 3 , the typical oxide composition percentages of blast furnace slag used in this study are as follows: CaO (41.6 wt%), MgO (7.68 wt%), SiO 2 (30.19 wt%), Al 2 O 3 (13.34 wt%), and Fe 2 O 3 (1.27 wt%).…”

This study focuses on utilizing ground granulated blast furnace slag (GGBS) from a steel plant as the main raw material, with water and calcium‐based montmorillonite as binders, with manganese and alkali metal nitrates (Na, K, Mg, Ca). A series of supported denitration catalysts are prepared using the equal volume impregnation method. These catalysts are then employed in the selective catalytic reduction process to investigate their impact on denitration effectiveness. Furthermore, the mechanism of low‐temperature denitration in selective catalytic reduction is analyzed by combining catalyst activity tests and characterization techniques. The activity of catalysts is assessed through Fourier transform infrared spectrometer (FT‐IR), X‐Ray diffraction (XRD), and search engine marketing (SEM) characterization tests, along with examining its denitration and sulfur resistance capabilities to determine the denitration mechanism. Experimental results indicate that Mn–Mg/GGBS exhibit the most efficient low‐temperature denitrification effect, and it demonstrates certain sulfur resistance with a 5% Mn loading and a 3% second active component. Introducing Ce as the third active component further enhances the sulfur resistance of Mn–Mg–Ce/GGBS when loaded at 1%.
