Modulated heterogeneous Fenton-like activity of ‘M’ doped nanoceria systems (M = Cu, Fe, Zr, Dy, La): Influence of reduction potential of doped cations

A novel low‐temperature NO removal approach with •OH from catalytic decomposition of H2O2 over La1‐xCaxFeO3 oxides

“…(d) and its values decreased with increased Ca stoichiometry. In previous reports, the decreased Eg was related with structure defects. It could be implied that the doped Ca significantly promoted the formation of oxygen vacancy in the as‐prepared catalysts.…”

A Detailed Insight into the Effects of Morphologies of Cerium Oxide on Fenton‐like Reactions for Different Applications

“…Some researchers discussed the homogeneous Fenton effect of metal oxides, where the dissolved transition metal ions became the original catalytic sites. [35,36] However, other studies proposed that Ce 3 + on the surface of CeO 2 was slightly soluble under mildly acidic conditions (even at pH 5.0) and made it difficult to exert homogeneous effects. [37] Therefore, it was widely accepted that the Fenton-like reaction induced by CeO 2 was a heterogeneous behavior where the decomposition of H 2 O 2 occurred on the surface of Ce 3 + .…”

A review on bio-electro-Fenton systems as environmentally friendly methods for degradation of environmental organic pollutants in wastewater

“…Cobalt, cerium, manganese, copper, and another redox metal oxides were utilized as catalysts to investigate their reactivity to H 2 O 2 degradation into cOH in the Fenton-like degradation of organic pollutants. [212][213][214][215] Cerium oxides (CeO 2 ) (such as CeO 2 nanorod and CeO 2 nanocube) as heterogeneous Fenton-like catalysts have been attracted great interest for their catalytic oxidation applications. 216 Additionally, Ce-doped MOF and CuO/Al 2 O 3 are also efficient heterogeneous Fenton-like catalyst with high activity in Fenton-like oxidation of hazardous pollutants.…”
