“…The comparison of the activities of the spinels prepared for this investigation with the data from the literature reveals that the MCF-S catalyst possesses excellent efficiency in the studied oxidation reactions. It shows lower “light-off” temperatures than single Co 3 O 4 oxide [ 42 ], SBA-15-supported binary Co-Mn-oxides [ 43 ], and copper, nickel, or manganese ferrites [ 23 , 44 ].…”

“…For example, ZnFe 2 O 4 shows normal cation distribution, NiFe 2 O 4 is a representative of inverse spinels, while MnFe 2 O 4 and CoFe 2 O 4 are partially inverse spinels and the degree of the inversion depends on the preparation conditions. Our previous paper it is reported the influence of the type of fuel used in solution combustion synthesis on the catalytic properties in VOCs oxidation of MnFe 2 O 4 [ 23 ]. It was found that specific structural and morphological characteristics of the prepared spinels are responsible for their oxidation properties at relatively low temperatures.…”

The present paper reports on MnCoFeO4 spinels with peculiar composition and their catalytic behavior in the reactions of complete oxidation of hydrocarbons. The samples were synthesized by solution combustion method with sucrose and citric acid as fuels. All samples were characterized by powder X-ray diffraction, N2-physisorption, scanning electron microscopy, thermal analysis, X-ray photoelectron spectroscopy, and Mössbauer spectroscopy. The catalytic properties of the spinels with Mn:Co:Fe = 1:1:1 composition were studied in reactions of complete oxidation of methane, propane, butane, and propane in the presence of water as model pollutants. Both prepared catalysts are nanosized materials. The slight difference in the compositions, structure, and morphology is due to the type of fuel used in the synthesis reaction. The spinel, prepared with sucrose, shows a higher specific surface area, pore volume, higher amount of small particles fraction, higher thermal stability, and as a result, more exposed active sites on the sample surface that lead to higher catalytic activity in the studied oxidation reactions. After the catalytic tests, both samples do not undergo any substantial phase and morphological changes; thus, they could be applied in low-temperature hydrocarbon oxidation reactions.

“…During the process, by mixing Zn (NO 3 ) 2 ·6H 2 O, Fe (NO 3 ) 3 ·9H 2 O and glycine, sparks were generated when heated to the critical temperature and the burned product formed into brown fluffy ZnFe 2 O 4 powder. Combined with the results of the expected morphology shown in Figure 2 , the advantages of the combustion synthesis method, like the convenience, environmental protection, economy, and high efficiency [ 17 ], mean it should be followed up to a certain extent in the synthesis of materials.…”

Demands for the detection of harmful gas in daily life have arisen for a period and a gas nano-sensor acting as a kind of instrument that can directly detect gas has been of wide concern. The spinel-type nanomaterial is suitable for the research of gas sensors because of its unique structure. However, the existing instability, higher detection limit, and operating temperature of the spinel materials limit the extension of the spinel material sensor. This paper reviews the research progress of spinel materials in gas sensor technology in recent years and lists the common morphological structures and material sensitization methods in combination with previous works.

Purpose Coconut shell has been used as an organic template for the synthesis of hydrotalcite catalyst. The performance of this catalyst was to produce biodiesel from waste cooking oil has been compared with the hydrotalcite catalyst which was synthesized using saccharose as template. Method Hydrotalcite was synthesized via combustion method with coconut shell and saccharose as template. The two main variables of the study are the catalyst organic template and the catalyst calcination temperature. Hydrotalcite was calcined at various temperatures, namely 550 ℃, 650 ℃ and 750 ℃ respectively. Biodiesel was produced via transesterification. Result It was found that hydrotalcite synthesized using coconut shell as template which calcined at a temperature of 650 ℃ produced a biodiesel yield of up to 93.25%, which is higher than hydrotalcite using saccharose as an organic template (74.14%). Conclusion Studies show that agricultural waste can serve as a better organic template in the synthesis of hydrotalcite which resulted in more biodiesel yield in transesterification reaction.
