One-Step Room-Temperature Synthesis of Bimetallic Nanoscale Zero-Valent FeCo by Hydrazine Reduction: Effect of Metal Salts and Application in Contaminated Water Treatment
Autor: Asmaa A. Koryam, Shaimaa T. El-Wakeel, Emad K. Radwan, Elham S. Darwish, Azza M. Abdel Fattah
Publikováno v: ACS Omega. 7:34810-34823
The effect of initial salt composition on the formation of zero-valent bimetallic FeCo was investigated in this work. Pure crystalline zero-valent FeCo nanoparticles (NPs) were obtained using either chloride or nitrate salts of both metals. Smaller N
