TiO2-supported metal oxide catalysts for low-temperature selective catalytic reduction of NO with NH3I. Evaluation and characterization of first row transition metals

Metal Oxide Nanoparticles Supported on Macro-Mesoporous Aluminosilicates for Catalytic Steam Gasification of Heavy Oil Fractions for On-Site Upgrading

“…It can be observed a reduction of the total acidity for the clay-supported catalysts after the metal oxide impregnation, and this could be due to the pores blockage by the metal oxide formation, decreasing the NH 3 diffusion and adsorption through the clay structure. Also, when comparing Ni-containing materials, higher acidity values are observed and is in agreement with Peña et al [82] who evaluated the supported metal oxide (Mn, Cu, Cr, Co, Fe, V, and Ni) in TiO 2 for catalytic reduction of NO with NH 3 and observed that TiO 2 -Ni catalyst offers a higher acidity in comparison with the Co supported catalyst.…”

Effect of manganese substitution on the structure and activity of iron titanate catalyst for the selective catalytic reduction of NO with NH3

“…8B [47]. With the increasing of Mn substitution amounts, the intensities of Mn 2p 3/2 and Mn 2p 1/2 peaks gradually enhanced due to the concentration increase of surface manganese species.…”

Manganese–niobium mixed oxide catalyst for the selective catalytic reduction of NOx with NH3 at low temperatures

“…V, Cr, Mn, Fe, Co, Ni, Cu) oxides have been investigated in the low-temperature SCR reaction. Among these, Mn-containing catalysts exhibited high catalytic activities, such as MnO x -CeO 2 [5,6], Cr-MnO x [7], Mn/TiO 2 [8][9][10][11][12], MnO x / Ce 0.5 Zr 0.5 O 2 [13], and Mn-Ce/ZSM-5 [14].…”
