(a) PXRD pattern obtained from the product confirming formation of the FeAs phase. (b) TEM image of the FeAs nanoparticles coated with a carbonaceous shell. (c) HRTEM image of an individual nanoparticle showing single crystalline nature. Inset shows a typical SAED pattern obtained from individual nanoparticle where the diffraction spots could be indexed to the FeAs phase. (d) XPS spectra obtained from the nanoparticles showing Fe2p and As3d peaks.
