The as-prepared Ni nanoparticles were characterized by TEM, XRD and Fourier transform infrared (FTIR) spectroscopy. The presence of modifiers is crucial for the synthesis of size- and shape-controlled phase pure Ni nanoparticles. The modification effects of single modifiers such as PEGs and SDS, and their composites were investigated and analyzed. Among single modifiers, the PEG-200 or PEG-600 is beneficial to fabricating irregular snowflake-like crystals, PEG-2000 beneficial to synthesizing dodecahedra crystals, PEG-6000 beneficial to synthesizing triangular crystals, and SDS beneficial to fabricating dodecahedra crystals and irregular snowflake-like crystals with smaller average particle size. Among the composite modifiers, coexisting of SDS and PEG-600 or PEG-6000 is beneficial to fabricating irregular snowflake-like crystals with bigger average particle size. The effects of the modifiers play an important role in the synthesis of Ni nanoparticles certified by FTIR spectroscopy. %K liquid phase reduction method %K nickel nanoparticle %K polyethylene glycol (PEG) %K soidum dodecyl sulfate (SDS)
