The preparation method of a photoanode can affect its water splitting property. Here, as examples, we prepared Ta3N5 photoanodes by an electrophoresis deposition (EPD) method and an oxidation and nitridation of Ta foil (ONTF) method. The light harvest, interfacial charge transfer, and charge separation of the two Ta3N5 photoanodes were analysed to gain insight into the role of the preparation method on the water splitting property. The results suggested that the ONTF-prepared Ta3N5 showed a higher solar energy conversion efficiency, arising from its better interfacial charge transfer efficiency and higher charge separation efficiency. The higher charge separation efficiency was mainly attributed to good electron transfer, and the inter-particle connectivity was key for the electron transfer in the photoanodes. Especially, the dense, small particle structure of ONTF-prepared Ta3N5 was beneficial for increasing the connectivity between inter-particles. This comparison of preparation methods can be used as a reference for future photoanode preparation to improve the water splitting property of photoelectrochemical cells.

BiVO4 is a promising photoanode material for the photoelectrochemical (PEC) oxidation of water; however, its poor charge transfer, transport, and slow surface catalytic activity limit the expected theoretical efficiency.
