A simple method to fabricate Bi nanoparticles by using redox reactions between sodium borohydride and ammonium bismuth citrate in the presence of soluble starch in water phase was developed. The results show that soluble starch is better than PVP in stabilizing Bi nanoparticles. The as-prepared Bi nanoparticles were characterized by Fourier transform infrared spectroscopy, transmission electron microscopy, energy-dispersive X-ray, and powder X-ray diffraction. The catalytic performance of the Bi nanoparticles for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) in the presence of sodium borohydride was studied. The effects of sodium borohydride concentration, initial 4-NP concentration, catalyst dose, and reduction temperature were also investigated.
