以硝酸铟为原料，六亚甲基四胺(H MT )为沉淀剂，采用一步水热法合成具有高催化活性的介孔氢氧化铟纳米晶。采用XRD、TEM、FT-IR和DRS等对样品的晶相结构、形貌和光学性能进行表征。以甲苯为模型物，测试氢氧化铟的光催化性能。结果显示其对甲苯的光催化活性要高于 TiO2(P25)，且非常稳定，使用12次后其对甲苯的降解仍然可达90%。同时探讨了介孔氢氧化铟纳米晶的光催化机理。
The mesoporous nanocubes of In(OH)3 was prepared by one-step hydrothermal method using In (NO3 )3 and hexamine (HMT)as the precursor.X-ray power diffraction (XRD),UV-Vis diffuse reflectance spectroscopy (DRS),Fourier transform infrared spectrometry (FT-IR)and transmission electron microscopy (TEM)were employed to investigate the structure,morphologies,and optical properties of samples.Toluene was used as a probe molecule to investigate the photocatalytic activity of the mesoporous nanocubes of In (OH)3 .The results showed that the photocatalytic activity of the mesoporous nanocubes of In(OH)3 was more stable and higher than that of Degussa P25.The degradation rate of toluene reached 90% under UV irradiation after the In(OH)3 was recycled used for 12 times.The mechanism of high activity of the mesoporous nanocubes of In(OH)3 was also discussed.
