In these studies we report the catalytic proficiency of two Eu and Pr doped CeO 2 nanoparticles on the thermal behaviour of powder AP and CSPs samples. A co-precipitation method was used for synthesizing Eu and Pr doped CeO 2 nanoparticles and they were characterized by XRD, FTIR, and SEM with EDX. The catalytic proficiency of both Eu and Pr doped CeO 2 nanoparticles were investigated by utilizing TG-DSC technique. The FWO, KAS, and Starink methods were used to determine activation energies of all catalyzed AP and CSPs samples. The catalytic proficiency increased by addition of Eu and Pr doped CeO 2 nanoparticles and decomposition temperature decreased in the presence of catalyst. The activation energy decreased by the addition of Eu and Pr doped CeO 2 nanoparticles in AP and CSPs, the burning rate of CSPs found to increase by the addition of Eu and Pr doped CeO 2 nanoparticles. The Pr doped CeO 2 nanoparticles showed good catalytic efficiency on AP and CSPs that reduced the decomposition temperature around 70 °C for AP and 20 °C for CSPs. The activation energy of CSPs catalyzed by Pr doped CeO 2 nanoparticles reported 150.12, 147.60, and 146.83 kJ mol −1 by FWO, KAS, and Starink method respectively which decreases in existence of catalyst in CSPs.

“…Raman band observed at 466 cm −1 in both CeO 2 NC and CeO 2 NC-O600 samples is reported to be attributed to the F 2g symmetrical stretching vibration mode of CeO 2 in the symmetrical breathing mode of the Ce−O8 vibration unit. 34 When the ceria nanocubes are modified with Pr before and after oxidation pretreatment, a clear shift of the F 2g band to lower frequencies of 451 cm −1 is observed. This shift may be attributed to two consequences of Pr modification.…”

In this work, a simple one-step thermal oxidation process was established to achieve a significant surface increase in {110} and {111} nanofacets on well-defined, pure and Pr-doped, ceria nanocubes. More importantly, without changing most of the bulk properties, this treatment leads to a remarkable boost of their enzymatic activities: from the oxidant (oxidase-like) to antioxidant (hydroxyl radical scavenging) as well as the paraoxon degradation (phosphatase-like) activities. Such performance improvement might be due to the thermally generated sawtoothlike {111} nanofacets and defects, which facilitate the oxygen mobility and the formation of oxygen vacancies on the surface. Finally, possible mechanisms of nanoceria as artificial enzymes have been proposed in this manuscript. Considering the potential application of ceria as artificial enzymes, this thermal treatment may enable the future design of highly efficient nanozymes without changing the bulk composition.

“…Therefore, a wide range of techniques with a lot of affecting parameters have been conducted for the synthesis, processing and sintering of ceramic materials. Similar to many oxide ceramic materials, CeO 2 have been synthesized by different approaches including sol‐gel, precipitation, hydrothermal, thermal decomposition, and combustion methods. As expected, different synthesis methods may lead to various structures, morphologies, properties and consequently, diverse potential applications.…”

In this study, combustion synthesis of cerium oxide nanoparticles was reported using cerium nitrate hexahydrate as starting material as well as urea, glycine, glucose, and citric acid as fuels. The influence of fuel type on structure, microstructure, band gap, and corrosion inhibition was investigated. X‐ray diffraction (XRD) patterns and scanning electron microscopy micrographs showed that CeO2 nanoparticles with different morphologies were obtained depending on the fuel type. Microstructural changes from unreacted gel to sponge‐like morphologies were resulted by varying the fuel type from urea, glycine, and glucose to citric acid. In addition to Ce–O bonds, Fourier transform infrared analysis showed carbon bonds of carbonaceous compositions from incomplete combustion which were declined during combustion reaction. Furthermore, corrosion analyses showed that samples synthesized using urea fuel released the most Ce+4 ions and could have better protection than other samples.
