光谱纯试剂(SP:Spectrum pure): 表示光谱纯净。 但由于有机物在光谱上显示不出,所以有时主成分达不到99.9%以上,使用时必须注意,特别是作基准物时,必须进行标定。 根据高纯试剂工业专用范围的不同,可将其分为以下几种: 1.光学与电子学专用高纯化学品 即电子级试剂(EIectronicgrade)试剂。 2.金属-氧化物-半导...

Titanium Dioxide (TiO2) nanomaterials have been used primarily as photocatalysts over past few decades, however, its wide band gap largely limited TiO2activity to the UV region of the solar spectrum. The discovery of ‘‘black’’ titanium dioxide nanoparticles with visible infrared absorption opened...
