The catalytic activity of photocatalyst is strongly dependent on the phase structures, grain size and particle morphology of the catalyst. In this paper, the controlled synthesis of bismuth(Bi) with different morphologies (nanoparticles, nanorods, nanocubes and micro-spheres) has been successfully realized by adjusting different experimental parameters. The Bi nanostructures were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy (FT-IR), Bruna...
