title: Effects of Annealing on the Microstructures and UV and Visible Light-Induced Photocatalytic Activities of Indium Hydroxide Nanocubes.
abstract: This work initiated a systematic study on the thermal treatment for In(OH)3 photocatalysts and its impact on their microstructures and photocatalytic properties. The phase transformation process from In(OH)3 to In2O3 was investigated by XRD, TG, DRS and ion etching XPS technologies. The results demonstrated that the formation of In2O3 phase occurred from surface to inside of bulk In(OH)3 and a heterojunction structure between In2O3 and In(OH)3 was formed. The variation of textural properties and the formation of heterojunction structure were crucial for the enhanced UV-light photocatalytic activities for RhB degradation, while the visible-light photocatalytic activity was mainly associated with the enhancement of the visible light absorbance capacity deriving from surfaced In2O3. The results may be extended to comprehend the structure-property correlations of hydroxide-containing photocatalysts and help to explore highly efficient photocatalysts towards thermal decomposition.
