“…These values shifted by 100 and 135°C, respectively, toward higher temperatures over noncoated mesh. It has been reported that a small quantity of 1,3-butadiene was selectively formed in the oxidation of n-C 4 H 8 at a temperature >350°C over MnMoO 4 -based catalysts upon C-H activation [26]. It should be noted that 1, 3-butadiene was not detected in the present work.…”

“…It is widely accepted that the catalytic performance of ferrite-type catalysts depends on their oxygen mobility, since the reaction follows the Mars-van-Krevelen mechanism [27]. The abundance of O ads could support in the catalytic oxidation process, as proposed by Veleva and Trifirò [26]. The obtained cauliflower surface structure with open porosity is expected to hold more oxygen and active sites and consequently could be beneficial for the catalytic reaction.…”

“…It should be noted that 1, 3-butadiene was not detected in the present work. According to Veleva and Trifirò [26], the initiation of n-C 4 H 8 oxidation occurred at around 350°C and O ads is responsible for the oxidation of n-C 4 H 8 to CO x . However, n-C 4 H 8 oxidation becomes measurable at relatively low temperature in this study.…”

“…The reactions involve alternate reduction and oxidation of the oxide on the surface with formation of surface oxygen vacancies (as the key step) and their replenishment by gas‐phase oxygen. It has also been reported that the abundance of the adsorbed oxygen at the surface of metal oxides could plays a determinant role in the catalytic oxidation process . In addition, the obtained well‐defined crystal structure featuring cubic and pyramidal shapes with open porosity is expected to hold more oxygen and active sites, consequently could be beneficial for the catalytic reaction.…”

Thin films of cobalt‐iron oxides (CoFe2O4) with spinel‐type structure were prepared by pulsed‐spray evaporation chemical vapor deposition (PSE‐CVD) using Fe(acac)3 and Co(acac)3 as precursors. The optimal depositions of CVD‐type growth have been established and such growth can be achieved at 400 °C. The obtained films have been systematically characterized in terms of structure (XRD and Raman), surface, and bulk composition (XPS and EDS) as well as morphology (SEM). CoFe2O4 has been successfully tested as an active catalyst toward total oxidation of CO, C3H6, dimethyl ether (DME), and n‐C4H8. The results indicate that both the lattice and adsorbed oxygen presented at the surface of the catalyst play determinant roles in the catalytic oxidation process.

“…T 50 and T 90 of n-C 4 H 8 oxidation over cobalt ferrite were observed at 358 and 402°C, whereas these values shifted by respective 100 and 135°C toward higher temperatures over NCM. It has been reported that a small quantity of 1,3-butadiene was selectively formed in the oxidation of n-C 4 H 8 at temperature higher than 350°C over MnMoO 4 -based catalysts [86]. It should be noted that 1,3-butadiene was not detected in the reaction with the PSE-CVD made Co 2.1 Fe 0.9 O 4 indicating that the material presents higher catalytic activity.…”

To reduce emissions and protect environment from pollution caused by volatile organic compounds (VOCs) and CO, catalytic oxidation can be applied as an efficient and promising technique. This review provides a novel and facile strategy to synthesize spinel-type and non-spinel-type transition metal oxides (TMOs). Specifically, single ) TMOs have been prepared using pulsed spray evaporation chemical vapor deposition approach (PSE-CVD). PSE-CVD offers several advantages over conventional methods, such as relatively low cost, simplicity and high throughput, which makes it a promising strategy. Moreover, the PSE delivery system allows using less stable precursors and permits improving the reproducibility of the film properties with tailored compositions. The above listed TMOs prepared by PSE-CVD were successfully tested as catalysts toward the complete oxidation of some real fuels such as CO, C 2 H 2 , C 3 H 6 , n-C 4 H 8 and C 2 H 6 O as representatives of VOCs and industrial exhaust streams. The active TMOs explored in this review could be potential catalysts candidates in one of the research areas that are currently under scrutiny, as the battle for the future of energy and environment involves the generation and application of clean energy.
