Abstract:
In this work, InVO4 hierarchical microspheres and InVO4 nanowires were successfully syn-thesized by a facile hydrothermal method. Field emission scanning electron microscopy showed that InVO4 crystals can be fabricated in different morphologies by simply manipu-lating the reaction parameters of hydrothermal process. The as-prepared InVO4 photocat-alysts exhibited higher photocatalytic activities in the degradation of rhodamine B under visible-light irradiation (λ>420 nm) compared with commercial P25 TiO2. Furthermore, the as-synthesized InVO4 hierarchical microspheres showed higher photocatalytic activity than that of InVO4 nanowires. Up to 100% Rh B (3μmol/L) was decolorized after visible-light irradiation for 40 min. In addition, the reason for the di erence in the photocatalytic activ-ities for InVO4 hierarchical microspheres and InVO4 nanowires was studied based on their structures and morphologies.
