Effect of anion on the homogeneous precipitation of precursors and their thermal decomposition to zinc oxide

Influence of Fe-doping on the structural, optical and magnetic properties of ZnO nanoparticles

“…The peak at 2358 cm À 1 is because of the existence of CO 2 in the air [19]. The absorption peak at 1102 cm À 1 is ascribed to the sulfate group [20], which agrees with the results from XPS. The peak at 434 cm À 1 in all the spectra are assigned to the Zn-O vibration while the peak at 621 cm À 1 , found only in the Fe-doped samples, is characteristic of a Fe-O stretch [21,22].…”

Effect of reducing agents on the structure of zinc oxide under microwave irradiation

“…Among which, ZnO has wide applications in the areas such as solar cells [2][3][4], catalysis [5,6], sensors [7], laser diodes [8] and varistors [5,9]. Various techniques had been employed for the synthesis of the nano/micro structured ZnO such as sol-gel process [10], homogeneous precipitation [5], thermal decomposition [11], microwave heating [12], conventional hydrothermal [13][14][15], etc.…”

Synthesis of CuO@NiO core-shell nanoparticles by homogeneous precipitation method

“…Among the reported preparation methods, solution based ones possess some advantages; they lead to materials with fine particle size, high purity and good homogeneity. Among the solution based methods, homogeneous precipitation has been widely used since one can easily control the particle size with the production of powders with uniform size [28][29][30]. In the homogenous precipitation method, the chemical composition and homogeneity of the produced mixed metal oxide nanoparticles depend on concentration of the reagents, pH, aging conditions and calcination temperature of the precursors [31,32].…”
