Nickel nanoparticles stabilized by polyvinylpyrrolidone (PVP) were synthesized through modifications to the polyol method. Controlling the Ni/reducing agent (NaBH4) ratio used in the synthesis led to different nanoparticles samples with average sizes of 3.4, 2.8 and 2.2nm. The crystalline structure, the presence of PVP and the size of the nanoparticles were confirmed using X-ray diffraction (XRD),...
