A novel strategy to enhance the visible light driven photocatalytic activity of CuBi2O4 through its piezoelectric response

Piezocatalysis is realized in hydrothermally-derived CuBi2O4 nanorods for the first time. Through bi-harvesting of photo- and vibration energies, 98.1% Rhodamine B (RhB) can be degraded, which is significantly higher than ∼38.7% from single photocatalysis and ∼72.8% from single piezocatalysis. The e...

Summary:Piezocatalysis is realized in hydrothermally-derived CuBi2O4 nanorods for the first time. Through bi-harvesting of photo- and vibration energies, 98.1% Rhodamine B (RhB) can be degraded, which is significantly higher than ∼38.7% from single photocatalysis and ∼72.8% from single piezocatalysis. The enhanced catalytic activity is attributed to the intensified separation of electron-hole under the piezoelectric potential. Results show that CuBi2O4 is promising catalyst to decompose the organic pollutant in nature water. •Piezocatalysis activity has been realized in CBO for the first time.•Harvesting light and vibration energy has been realized in CBO.•Bi-catalytic degradation of RhB is higher than photocatalysis or piezocatalysis.•h + become the most important active specie instead of ·OH.
