Abstract
Two-dimensional nanoplates were controllable synthesized by a hydrothermal process. An enhancement in the photo-to-current efficiency was observed over the two-dimensional nanoplate thin-film photoelectrode with comparison to that of a solid state prepared electrode. Scanning electron microscopy images showed that the photoelectrode with a uniform surface morphology can be prepared using nanoplate powder, which is beneficial for the transportation of photogenerated electrons to the surface due to the low boundary loss in the nanoplate thin film. The repulsive force increases due to the local structure variation of nanoplates are considered to be the intrinsic factor for the enhancement of photo-to-current efficiency.Keywords
