Synthesis of porous spherical AgBr nanoparticles in the presence of gelatin using AgCl as the precursor
چکیده انگلیسی

Porous spheres of AgBr nanoparticles with an average diameter of 150–200 nm have been prepared by a simple reaction between AgCl suspension and KBr in the presence of gelatin at 10 °C. Gelatin played a decisive role as an inhibitor of the direct attack of Br− ions to AgCl surfaces and coagulation of the growing AgBr in producing the porous spheres at lower temperature. The products were characterized by X-ray powder diffraction, transmission electron microscopy and X-ray photoelectron spectra techniques.
