Synthesis of Bismuth Oxide Nanoparticles by Solution Combustion Method

Hydrazine and Urea Fueled-Solution Combustion Method for Bi2O3 Synthesis: Characterization of Physicochemical Properties and Photocatalytic Activity

“…With rapidly increasing research on bismuth oxide, more methods of Bi2O3 synthesis have now been discovered. These methods include deposition [11], sol-gel [14], hydrothermal [15], solution combustion [16][17][18], magnetron sputtering deposition [19], and low-temperature electrodeposition [20]. In this study, solution combustion method (SC) was used in consideration of its time and energy savings and simple production of the desired material.…”

“…Researches on synthesis of TiO2 and NiO by solution combustion method using urea and glycine as fuels were conducted; however, synthesis of bismuth oxide using the solution combustion method with fuel urea and hydrazine has never been undertaken previously. Astuti et al [17] and La et al [18] have synthesized it but the fuel used was different, that was only citric acid. Therefore, it is important to study the effect of fuels, especially hydrazine and urea on the characteristics of the obtained products; these characteristics are important to determine the potential application of bismuth oxide primarily as photocatalysts.…”

“…TG‐DTA curve of Bi 2 O 3 is shown in Figure 2D. DTA curve showed an endothermic peak at 402 °C due to trace amount of phase transformation of meta stable to stable Bi 2 O 3 (normally β to α form) 33.…”

“…Nanocrystalline Bi 2 O 3 was synthesized following the reported solution combustion method with a slight modification 33. Briefly, Bi(NO 3 ) 3 ⋅5H 2 O (2.9106 g) and citric acid (1.471 g) were dissolved in 10 mL HNO 3 (0.04 mM) and then polyethylene glycol (PEG) (0.04 g) was added to the above mixture.…”

Studying Impact of Different Precipitating Agents on Crystal Structure, Morphology and Photocatalytic Activity of Bismuth Oxide

“…The deposition method determines whether the catalyst is uniformly distributed on the support or accumulation of the oxide takes place on the areas of the support [10,11,12]. Therefore, various methods have been reported for synthesis Bi2O3 that include hydrothermal [13], direct precipitation [14][15][16][17][18][19], microwave [6,20], solution combustion [21,22], and sol gel [1]. Of all these methods, described for the synthesis of Bi2O3 particles, the precipitation method is one of the least complex and energy efficient.…”
