Indium oxide [In2O3] nanocubes were obtained through thermal treatment of the hydrothermally synthesized indium hydroxide [In(OH)3] nanocubes. The photocatalytic activities of In(OH)3 and In2O3 nanocubes have been evaluated by the degradation of crystal violet in an aqueous solution. The degradation rate of crystal violet under UV irradiation in In2O3 containing aqueous is much higher than that in In(OH)3 aqueous, which may be attributed to the formation of more defects as well as more active sites for interactions after thermal treatment of In(OH)3.
Graphical abstractIn(OH)3 and In2O3 nanocubes were synthesized via hydrothermal method. Their photocatalytic activities were studied according to the degradation of crystal violet aqueous solution under UV irradiation. The as-prepared In2O3 nanocubes show more extremely photocatalytic activity than In(OH)3 nanocubes which is possibly due to forming a larger surface area and more defects on the surface of In2O3 nanocubes during heat treatment of In(OH)3.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► In(OH)3 and In2O3 nanocubes were synthesized via hydrothermal method. ► The In2O3 nanocubes show more extremely photocatalytic activity than In(OH)3 nanocubes. ► The photocatalytic mechanism is explained.
