TL;DR: In this article, a co-precipitation method was used for synthesizing Eu and Pr doped CeO2 nanoparticles and they were characterized by XRD, FTIR, and SEM with EDX.
Abstract: In these studies we report the catalytic proficiency of two Eu and Pr doped CeO2 nanoparticles on the thermal behaviour of powder AP and CSPs samples. A co-precipitation method was used for synthesizing Eu and Pr doped CeO2 nanoparticles and they were characterized by XRD, FTIR, and SEM with EDX. The catalytic proficiency of both Eu and Pr doped CeO2 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 CeO2 nanoparticles and decomposition temperature decreased in the presence of catalyst. The activation energy decreased by the addition of Eu and Pr doped CeO2 nanoparticles in AP and CSPs, the burning rate of CSPs found to increase by the addition of Eu and Pr doped CeO2 nanoparticles. The Pr doped CeO2 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 CeO2 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.

TL;DR: In this paper, a review of the kinetics of decomposition of certain inorganic oxides and sulphides and a few related compounds is presented, including the gas and liquid phase and reactions of neutral species.
Abstract: Publisher Summary This chapter reviews the kinetics of decomposition of certain inorganic oxides and sulphides and a few related compounds. It discusses the gas and liquid phase and to the reactions of neutral species. Reactions and rate coefficients are numbered consecutively throughout the chapter and the reaction number appearing as a subscript in the symbol for the corresponding rate coefficient. The decomposition compounds that are considered are C 3 O 2 , CO, CO2 , CS 2 , COS, CSe 2 , COSe, N 2 O, NO, N 2 O 3 , NO 2 (N 2 O 4 ), N 2 O 5 , HNO 2 , HNO 3 , O 3 , SO 2 , SO 3, F 2 O, F 2 O 2 , Cl 2 O, ClO 2 , C1 2 O 6 , Cl 2 O 7 , and HClO . The chapter also emphasizes on the investigation of the photolytic decompositions of some of these compounds that are thought to provide useful sources of atoms (C, O, S and Se) and free radicals (C 2 O). The photochemistry of carbon dioxide has particular relevance to the chemistry of planetary atmospheres, although to date the mechanism of CO 2 photolysis remains obscure.
