The enhancement of photocatalytic reactivity through the internal electric field has received much attention. combination piezoelectric effect and photo-exiting process facilitates segregation photogenerated carriers, thereby boosting piezo-photocatalytic activity. We have constructed g-C3N4/Ag/ZnO tri-component composites; with various g-C3N4 precursors to achieve reliable photo/piezo-photocatalysis for H2 production Rhodamine B (RhB) dye degradation. observed that urea-based (UCAZ) tri-components exhibit a superior rate 1125.5 μmol h-1 g-1 under conditions. When piezoelectric-potential was introduced into photocatalysis reaction via ultrasonic, increased dramatically 1637.5 g-1, which is approximately 145% greater than light irradiation alone. Similarly, catalytic decomposition ratio coexistence ultrasound light, degradation efficiency reached 99% in 120 min, higher value (42%, 0.0031 min-1) piezo-catalysis (80%, 0.01 condition constant synergistic simulation reaches 0.021 min-1, 200% 645% times sole ultrasonic illumination. Additionally, RhB all performed solar (Sunlight) irradiation, 99.5% 45 min 0.06 300% LED source. enhanced performance tricomponent attributed high specific surface area (168 m2 g-1) synergetic piezo catalysis photocatalysis.
