Solution Combustion Synthesis as a Novel Route to Preparation of Catalysts

Structural, magnetic, and dielectric properties of solution combustion synthesized LaFeO3, LaFe0.9Mn0.1O3, and LaMnO3 perovskites

“…Calculations for the required amounts of reactants for the combustion reaction in SCS method were done as per the literature. 28,29 LaFeO 3 was synthesized by this route using La(NO 3 ) 3 and Fe(NO 3 ) 3 as precursors, and ODH as fuel. Typically, in a 300 mL borosilicate petridish, 2 g of La(NO 3 ) 3 , 1.86 g of Fe(NO 3 ) 3 , and 1.16 g of ODH were dissolved in water, and placed in a muffle furnace which was preheated at 300 1C.…”

“…17 Among these synthesis routes, solution combustion synthesis (SCS) has drawn considerable recognition for its simple nature, cost-effectiveness, energy-and time-saving feature, and production of pure homogeneous nano-sized solid materials. 28,29 In this method, an oxidizer (metal salts such as nitrates, carbonates, acetates, and sulfates, etc.) and a fuel (usually urea, glycine, citric acid, oxalyl dihydrize, etc.)…”

“…In this sense, it should also be noted that ODH has been used as a fuel in the SCS process to prepare several oxide materials. 29 There are several reports regarding the preparation of undoped and doped LaFeO 3 materials via solution combustion synthesis in the literature. [12][13][14][15]24,25,27 However, in several preparations, glycine, 12,15 sorbitol, 13 ethylene glycol, 14 stearic acid, 24 and citric acid 25,27 have been used as fuels.…”

Direct Reduction in Greenhouse Gases by Continuous Dry (CO2) Reforming of Methane over Ni-Containing SHS Catalysts

“…Unique materials were developed by controlled high-temperature combustion as a result of synthesis by SHS [24]. The SHS method offers a unique method for the preparation of modern, highly active ceramic catalysts, as well as carriers with controlled composition and properties which satisfy the special requirements of various types of reactions [25][26][27][28][29][30][31][32][33][34][35][36][37]. The combustion temperature can reach up to 3000 • C (depending on the composition of the system) due to the exothermic reactions that occur within just a few minutes after the start of SHS synthesis.…”

Ni-Al-Mg-Mn COMPOSITE CATALYSTS FOR PARTIAL OXIDATION OF NATURAL GAS

“…For the above processes, oxide catalysts [1], their mixtures, and composites based on them [2] have been recently used instead of the noble metals [3,4] that were used previously. The method of self-propagating high-temperature synthesis has become widespread in recent years [5], especially its modification -the solution combustion synthesis (SCS) [6][7][8], as a result of which finely dispersed oxides and spinels are synthesized [9,10].…”
