摘要
稀散金属铟主要富集于硫化矿物中,少量存于锡石矿中,提取不易[1].铟广泛作为液晶显示用的透明导电膜ITO(In2O3/SnO2),近年来,随着电子工业的快速发展,铟锡氧化物纳米材料的研究成为人们关注的热点[2].纳米ITO可用作隐身材料、太阳能电极材料和收集器等,具有优异的性能和十分诱人的研究前景.Kim等[3]以In(NO3)3·xH2O和SnCl4·xH2O为原料,用共沉淀法合成了立方结构的纳米ITO粉.但目前使用微波辐射制备铟锡氧化物网状纳米粉体尚未见文献报道.
By using ultrasonic and chemical liquid coprecipitation, the precursor was prepared with high purity In, SnCl4·5H2O and urea. The In2O3·SnO2 nanonets we re obtained from precursor by heating in microwave oven. The powders were charac terized by XRD, TEM. The analyzed results show the sample is In2O3·SnO2, and In 2O3 is rhombohedral system while SnO2 is tetragonal system. The sample is in sph erical grain shape, with average granularity of 35 nm, and the mesh diameter of 10~80 nm. The sample was with fluorescence and good photocatalytic performance f or degradation of organic dyestuff.
