In this work, the bi-harvesting of light and vibration energy is realized in hydrothermally-synthesized ZnO nanorods which is designed to achieve photo-/piezo-bi-catalysis for dye decomposition. In the presence of both UV irradiation and vibration, the decomposition ratio of ZnO nanorods for acid orange 7 is similar to 80.8% within 100 min, which is higher than the value of similar to 56.7% for photo-catalysis or the value of similar to 31.8% for piezo-catalysis. The enhanced photo-/piezo-bi-catalysis of ZnO nanorods in dye decomposition can be attributed to that the piezoelectric potential which formed in piezocatalysis process can help separate the photogenerated electron-hole pairs, therefore achieving a synergy effect between photocatalysis and piezocatalysis. The excellent photo-/piezo-bi-catalysis of ZnO can potentially find application in enhancing catalytic efficiency of dye decomposition through harvesting the light and vibration energy present in natural environments.
