Abstract

TiO nanopowders modified by Nd and Sm were prepared using the sol-gel technique. It was found by XRD analysis that the samples containing Sm are amorphous up to 300 °C, while those with Nd preserve a mixed organic-inorganic amorphous structure at higher temperatures (400 °C). The TiO (rutile) was not detected up to 700 °C in the presence of both modified oxides. TiO (anatase) crystals found at about 400 °C in the Sm-modified sample exhibited an average crystallite size of about 25-30 nm, while doping with Nd resulted in particles of a lower size-5-10 nm. It was established by DTA that organic decomposition is accompanied by significant weight loss occurring in the temperature range 240-350 °C. Photocatalytic tests showed that the samples heated at 500 °C possess photocatalytic activity under UV irradiation toward Malachite green organic dye. Selected compositions exhibited good antimicrobial activity against K12 and .

摘要

采用溶胶-凝胶法制备了 Nd 和 Sm 改性的 TiO 纳米粉末。XRD 分析发现，含 Sm 的样品在 300°C 以下为非晶态，而含 Nd 的样品在较高温度（400°C）下保持混合有机-无机非晶态结构。在两种改性氧化物存在的情况下，TiO（金红石）在 700°C 以下均未检测到。在 Sm 改性样品中，约 400°C 时发现的 TiO（锐钛矿）晶体的平均晶粒尺寸约为 25-30nm，而掺杂 Nd 则导致粒径较小-5-10nm。DTA 表明，有机分解伴随着在 240-350°C 温度范围内发生的显著重量损失。光催化测试表明，在 500°C 加热的样品在紫外光照射下对孔雀石绿有机染料具有光催化活性。选择的成分对 K12 和 表现出良好的抗菌活性。
