Two-dimensional Bi 2 MoO 6 nanoplates were controllable synthesized by a hydrothermal process. An enhancement in the phototo-current efficiency was observed over the two-dimensional Bi 2 MoO 6 nanoplate thin-film photoelectrode with comparison to that of a solid state prepared Bi 2 MoO 6 electrode. Scanning electron microscopy images showed that the photoelectrode with a uniform surface morphology can be prepared using Bi 2 MoO 6 nanoplate powder, which is beneficial for the transportation of
