Synthesis and characterization of CuInS2 nanostructure by ultrasonic-assisted method and different precursors

Evaluating the efficiency of the GO‐Fe3O4/TiO2 mesoporous photocatalyst for degradation of chlorpyrifos pesticide under visible light irradiation

“…Moreover, no impurity peaks of other phases are detected, which shows the high purity of the sample. The average crystallite sizes ( D ) of the Fe 3 O 4 nanoparticle and TiO 2 mesoporous were calculated from the full‐width at half‐maximum (FWHM) using the Debye–Scherer formula: where D is the crystallite size, λ is the X‐ray wavelength of Cu Kα radiation, β is FWHM in radians, and θ is the Bragg's angle. The estimated mean crystallite size of the Fe 3 O 4 nanoparticle is 14 nm and the crystallite size of the TiO 2 is 31 nm.…”

Hydrothermal Synthesis of Rod-Like LaOCl Nanoparticles from New Precursors

“…On the other hand, weak absorption peaks in 1,479 and 1,417 cm -1 range are related to stretching frequency carbonate ion that has been absorbed from air [26]. Moreover, absorptions at 2,951 and 2,849 cm -1 are related to C-H bond, while the bands at 3,429 and 1,628 cm -1 are characteristic of the stretching vibrations of carboxyl groups C=O and O-H, respectively [27][28][29][30]. Finally, the band at 925 cm -1 is related to N-H (NH 2 ) bending vibrations [25].…”

Synthesis of micro sphere-like bismuth nanoparticles by microwave assisted polyol method; designing a novel electrochemical nanosensor for ultra-trace measurement of Pb2+ ions

“…[1][2][3][4][5][6][7][8] The use of organic surfactants in nanoparticles synthesis has been a popular method for achieving morphological control. [9][10][11] One of the most common and facile approaches that utilize this technique is the polyol method. 12 Initial studies concerning the polyol method focused on the preparation of elemental metals and alloys by exploiting the reducing properties of a high-boiling alcohol (i.e., glycerol or glycol) towards a suitable metal precursor.…”
