Low temperature synthesis of bismuth ferrite nanoparticles by a ferrioxalate precursor method

Effects of Mn Doping on Structural and Magnetic Properties of Multiferroic BiFeO3Nanograins Made by Sol-gel Method

“…1(a)). It can be explained that during auto ignition process the excess of carbonaceous materials inevitably give rise to the formation of impurity phases [11][12][13] [15]. As seen in Fig.…”

Effect of synthesis conditions on the preparation of BiFeO3 nanopowders using two different methods

“…To obtain nano-crystalline powders with high homogeneity and uniform structure, many techniques have been provided for the synthesis of the BiFeO 3 powders. These methods are coprecipitation [8], hydrothermal [9][10][11][12][13][14], solvothermal [15,16], sonochemical [17], microemulsion [17], polyacrylamide gel [18], ferrioxalate [19], sol-gel [6,[20][21][22][23], combustion synthesis [7,[24][25][26], molten-salt [27][28][29], tartaric acid-assisted gel strategy [30], polymeric precursor [31,32] and mechanochemical synthesis [33]. The chemical co-precipitation method ensures proper distribution of the various metals ions resulting to stoichiometric and smaller particles size product, compared to some of the other procedures.…”

Structural, Magnetic and Dielectric Properties of Sm3+ and Mn2+ Co-doped BiFeO3 Nanoparticles

“…Therefore, BFO-based photo catalysts are very reactive to visible-light and exhibit higher photo catalytic efficiency in visible range compared to the TiO 2 -based photo catalysts. To further improve the photo catalytic Performance, efforts have been made for band-gap engineering by different elemental doping onto the BFO lattice sites [9]. In order to prepare BFO nanoparticles of small sizes (<60 nm), several alternative chemical synthesis routes were adopted such as ferrioxalate precursor method [10], micro-emulsion technique [11], citrate-gel method [12], sol-gel method [8,13] , La 3+ and Mn 2+ have been doped onto BFO in order to improve its morphology, electrical and magnetic properties [14][15][16][17][18][19][20][21][22][23].…”
