“…One such catalyst is manganese-based, which has garnered attention due to its excellent low-temperature denitration activity. [21][22][23] Manganese-based catalysts exist in two main forms based on different loading methods: unsupported manganesebased catalysts and supported manganese-based catalysts.

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%.

“…A huge amount of nanoparticles have emerged in our daily life, in every field from drugs and electronics to paints and beauty care, and they are now arising in the field of catalysis. 9 They offer an alternative to conventional catalysts by offering large surface-to-volume ratio relative to bulk materials. 10 Recently, graphene oxide-based nanomaterials, because of p-p stacking in the carbon structure, have contributed significantly towards biosensors and in drug delivery systems.…”
