Photoelectrochemical performance of Ag3PO4/Ag membranes synthesized by grind coating

Photoelectrochemical (PEC) performance of Ag3PO4 microparticles (MPs) were evaluated by constructing a three-electrode cell with porous Ag3PO4 film as the photoanode. A simple grind-coating deposition route was developed to synthesize the Ag3PO4 films, which displayed excellent PEC activity and stability, even after a 400 °C or 500 °C annealing process. Excellent PEC performance was mainly attributed to a high adhesion between the film and substrate, and formation of a Ag3PO4/Ag junction. Moreover, n-type conduction behavior was identified by characterizing the Mott–Schottky (M–S) plots of a Ag3PO4 film synthesized via grind-coating. Finally, the grind-coating route was used for preparing the BiVO4 film photoanodes, of which the PEC performance was compared with those of Ag3PO4 films.
