Catalytic activity of gold nanoparticles supported on KNbO3 microcubes

- Gold NPs were prepared on KNbO3 microcubes that were hydrothermally prepared.
- Structural and electronic properties of Au/KNbO3 were systematically characterized.
- Au/KNbO3 was evaluated toward H2O2 decomposition and methylene blue degradation.
- Au particle size, reaction pH, and the interaction between Au and KNbO3 play a role.
