Low-temperature efficient degradation of ethyl acetate catalyzed by lattice-doped CeO2–CoOx nanocomposites

Cooperative Effect of the Ce–Co‐Ox for the Catalytic Oxidation of Toluene

“…It might be due to the high dispersion of Co nanoparticles beyond the detection limit or the existence of amorphous metal species . Moreover, the ionic radius of Co 2+ (0.820 Å) and Co 3+ (0.650 Å) were smaller than that of Ce 4+ (1.110 Å) . Therefore, the Co ions might be incorporated into the CeO 2 lattice to form the Ce−Co‐O x solid solution, which might also be confirmed by the slight shift (0.15 °) of the characteristic peak of CeO 2 (111) at 28.6° in Figure b.…”

Recent Advances in the Catalytic Oxidation of Volatile Organic Compounds: A Review Based on Pollutant Sorts and Sources

“…This was associated with the enriched lattice oxygen. 760 Catalytic oxidation of EA over noble metal (Pt, Ru and Au) supported catalysts were also reported in several works. 516,709,[761][762][763][764] In general, supported Ru catalysts show higher acitivity in this reaction compared with Pt-and Au-based catalysts.…”

Controllable construction of Ce‐Mn‐Ox with tunable oxygen vacancies and active species for toluene catalytic combustion

“…Considering the smaller radii of Mn 3+ (0.65 Å) and Mn 4+ (0.53 Å) than that of Ce 4+ (1.11 Å), this led to the formation of Ce‐Mn‐O solid solution. [ 43–45 ] The presence of the solid solution was considered to promote the emergence of structural defects (such as oxygen vacancies), which could increase the oxygen storage/release capacity of catalysts, resulting in better catalytic oxidation activity. The effect of different hydrothermal conditions on the structure of Ce‐Mn‐O x catalysts therefore might lead to different element valence states and redox properties, which was discussed in detail below.…”
