相比纳米晶体,氧化铟分级结构具有大比表面积,能够提供更多的反应活性位置,因而在光电、催化剂、气敏元件等领域有广阔的应用前景。本研究系统地综述了分级结构C-In2O3纳微粒子和H-In2O3纳微粒子的水热法制备,及其在光催化和气敏性方面的应用,最后给出了氧化铟分级结构潜在的发展前景。 Compared with nanocrystals, the indium oxide hierarchical structure has a large specific surface area and can provide more reactive sites, so it has broad application prospects in optoelectronics, catalysts, gas sensors and other fields. In this study, we systematically reviewed the hydrothermal preparation of graded C-In2O3 nanoparticles and H-In2O3 nano-particles and their applications in photocatalysis and gas sensitivity. Finally, the potential development of indium oxide grading structure was presented.
