rh-In(2)O(3) Nanoparticles for Efficient Photocatalytic Degradation of Rifampin

[Image: see text] 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 In(2)O(3) 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 In(2)O(3) and P25–TiO(2). Furthermore, the probable pathway and the feasible mechanism for the degradation of rifampin were also deeply explored and discussed.
