A method of preparing Bi2S3 nanoparticles by arrested precipitation is described. It is shown that varying the amount of stabiliser employed in the preparation controls the size of the particles. The as-prepared nanoparticles may be self-assembled on a tin oxide substrate. Photocurrent studies of the Bi2S3 modified electrode indicate that the presence of an oxidisable surface trap at approximately −0.15 V vs. Ag|AgCl|3.0 mol dm−3 NaCl. Photocurrent spectra indicate that the band edge of the Bi2S3 particles is only weakly dependent on particle size, consistent with a high effective mass of electrons in this material.
