rh-In₂O₃ Nanoparticles for Efficient Photocatalytic Degradation of Rifampin

Photodegradation, a widely accepted and promising technology, has gained significant attention for addressing the escalating concerns of environmental deterioration. In this article, rhombohedral corundum-type In₂O₃ nanocrystals were obtained from the transformation of InOOH via a simple calcining process. Under ultraviolet light irradiation, they showed higher photocatalytic activity in the decomposition of rifampin compared to that of the cubic phase In₂O₃ and P25-TiO₂. Furthermore, the probable pathway and the feasible mechanism for the degradation of rifampin were also deeply explored and discussed.
