Figure 8. Synergistic catalysis for H2 production. Schematic diagram of (A) energy band bending of catalyst and (B) carrier behavior within catalyst during piezo-photocatalysis. Figure A and B are quoted with permission from Han et al.[58]; (C) Experimental and simulated piezo-photocatalytic H2 production rate and selectivity of Pt/ZnIn2S4/BaTiO3 heterojunctions, and (D) corresponding H2 evolution mechanism. Figure C and D are quoted with permission from Wang et al.[59]; (E) Schematic illustration of the piezopotential switch mechanisms, and (F) corresponding H2 production rates under ultrasonication-light (U-L) and stirring-light irradiation (O-L) with the working current of 0.8 and 0.2 A, respectively. Figure E and F are quoted with permission from Jin et al.[61]; (G) Schematic representative of the synergistic pyro-photocatalytic water splitting over BaTiO3 photoanode, and (H) corresponding
